appareils numériques de la classe B prescrites dans le Réglement sur le brouillage radioélectrique édicté par le
Ministère des Communications du Canada.
Wireless Usage and Requirements
Radio transmitting type devices (RF module) are present in models with the wireless option. These devices
operate in the 2.4 GHz band (i.e. 802.11b/g WLAN & Bluetooth).
As a general guideline, a separation of 20 cm (8 inches) between the wireless device and the body, for use of a
wireless device near the body (this does not include extremities) is typical. This device should be used more than
20 cm (8 inches) from the body when wireless devices are on and transmitting.
Some circumstances require restrictions on wireless devices. Examples of common restrictions include:
•
When in environments where you are uncertain of the sanction to use wireless devices, ask the applicable
authority for authorization prior to use or turning on the wireless device.
•
Every country has different restrictions on the use of wireless devices. Since your system is equipped with a
wireless device, when traveling between countries with your system, check with the local Radio Approval
authorities prior to any move or trip for any restrictions on the use of a wireless device in the destination
country.
•
Wireless devices are not user-serviceable. Do not modify them in any way. Modification to a wireless device
will void the authorization to use it. Please contact the manufacturer for service.

Introduction
®
®
®
Wyse thin clients running Microsoft Windows XP Embedded provide access to
applications, files, and network resources made available on machines hosting Citrix™
ICA and Microsoft™ RDP session services. The thin clients contain a full featured Internet
®
Explorer browser and thin client emulation software, Ericom – PowerTerm TEC. Other
locally installed software permits remote administration of the thin clients and provides
local maintenance functions. Additional Addons are available that support a wide range of
specialty peripherals and features for environments needing a secure Windows user
interface with 32-bit Windows compatibility.
Session and network services available on enterprise networks may be accessed through
a direct intranet connection, a dial-up server, or an ISP which provides access to the
Internet and thus permits the thin client to connect to an enterprise virtual private network
(VPN) server.

Establishing a Server Environment
This chapter contains information on the network architecture and enterprise server
environment needed to provide network and session services for Wyse thin clients running
Microsoft Windows XP Embedded. It also includes information to help you address
important considerations when configuring access to the server environment and when
configuring the services to be provided by the server environment.
Setting-Up Access to the Enterprise Servers
There are five basic methods of access to the enterprise server environment available to
the thin client. Except for Ethernet Direct, all of the access methods require that some
local settings be made on the thin client. These local settings are retained and are
available for the next thin client system start. Activating these local settings and the
defined connections can also be automated at thin client system start.
Methods of access include:
•
Ethernet Direct - This is a connection from the thin client Ethernet port directly to the
enterprise intranet. No additional hardware is required. In this configuration all network
services can be used, including an enterprise DHCP server. A DHCP server on the
network can provide not only the thin client IP address, but also the location of the file
•
Wireless Direct - A supported wireless adapter (or the optional internal wireless
feature) can be used to access the enterprise intranet. A wireless adapter uses
short-range wide-band radio to communicate with a wireless access point. Typically,
wireless access points are located at several locations in the enterprise within range of
the wireless adapters and directly connected to the enterprise intranet. For more
information on configuring wireless network devices or the optional thin client internal
wireless feature, refer to "Configuring Wireless Local Area Network (LAN) Settings"
•
•
PPPoE - Thin client support for PPPoE is intended for devices which connect to the
Internet directly from remote locations. The New Connection Wizard (available by
clicking Start | Control Panel, double-clicking the Network Connections icon, and
then clicking the Create a new connection link) can be used to configure and invoke a
PPPoE connection. Once connected, all packets are through a PPP connection over
Ethernet to the DSL modem. For more information on the New Connection Wizard,
Dial-up Modem - A dial-up modem can be used with the thin client to access a dial-up
server. The dial-up server must be a Microsoft Remote Access Server or another
server that supports industry-standard protocols. The dial-up server can provide either
of the following methods of access to the enterprise intranet:
•
•
An enterprise dial-up server will directly connect to the enterprise intranet.
An Internet Service Provider (ISP) dial-up server simply provides access to the
Internet, from which the thin client accesses an enterprise PPTP VPN server that
connects to the enterprise intranet.

Chapter 2
•
PPTP VPN - PPTP (Point-to-Point Tunneling Protocol) is a network protocol that
enables the secure transfer of data between a remote client (in this case the thin client)
and an enterprise server environment by creating a virtual private network (VPN)
across TCP/IP-based data networks such as the Internet. It provides a
password-protected path through the enterprise firewall to the enterprise server
environment in which the network and session services required by thin clients reside.
The New Connection Wizard (available by clicking Start | Control Panel,
double-clicking the Network Connections icon, and then clicking the Create a new
connection link) can be used to configure and invoke a VPN connection.
An Internet Service Provider (ISP) must be available to provide access to the Internet.
Any of the standard means of connecting to the ISP may be used, such as a dial-up
modem, cable modem, and DSL modem. The connection to the ISP must be
established first, before contacting the enterprise PPTP VPN server. This includes
dial-up access as well as direct access through the cable modem and DSL modem
paths. For more information on the New Connection Wizard, refer to documentation on
Understanding How to Configure Your Network Services
Network services used by the thin client can include DHCP, FTP file services, and DNS.
How you configure your network services depends on what you have available in your
environment and how you want to design and manage it.
The following topics in this section provide important information to help you configure
your network services:
•
•
•
Using Dynamic Host Configuration Protocol (DHCP)
A thin client is initially configured to obtain its IP address and network configurations from
a DHCP server (new thin client or a thin client reset to default configurations). A DHCP
server can also provide the IP address or DNS name of the FTP server and the FTP
root-path location of the Addons (in Microsoft .msi form) for access through the DHCP
upgrade process. Using DHCP to configure and upgrade thin clients is recommended and
saves you the time and effort needed to complete these processes locally on multiple thin
clients (if a DHCP server is not available, fixed IP addresses can be assigned and must be
entered locally for each device). A DHCP server can also provide the IP address of the

Using FTP File Servers
Windows XP Embedded WFR2 includes an FTP Upgrade utility that can be used to
upgrade the XP Embedded thin client with Addons which are in Microsoft .msi form. This
utility allows you to automatically or manually upgrade a thin client by downloading MSI
packages from a specified FTP server. The MSI packages are stored on the FTP server in
a directory in the FTP root path (this FTP file server name and root-path directory must be
made available to the thin client). To select the upgrade options you want, use the FTP
Use the following guidelines to set up your servers:
•
Automatic upgrades - Params.ini and the MSI package must be present on your FTP
server (in the same path) to upgrade the thin client.
•
DHCP upgrades - If the DHCP server is supplying the location of the MSI package, be
server list and 162 - Root path to the FTP files).
•
•
Anonymous log-on capability - The FTP server must provide anonymous log-on
capability.
User ID and Password - In the FTP Addon Installer dialog box, the default User
name is anonymous and the default Password is Wyse.
Note
Use of DHCP is recommended. However, if a DHCP server is not available,
fixed IP addresses (FTP Path) can be assigned using the FTP Addon
Installer dialog box on the thin client.

Using DNS
Thin clients accept valid DNS names registered on a DNS server available to the
enterprise intranet. The thin client will query a DNS server on the network for name to IP
resolution. In most cases DNS is not required but may be used to allow hosts to be
accessed by their registered DNS names rather than their IP addresses. Every Windows
DNS server in Windows 2000 and later includes Dynamic DNS (DDNS) and every server
registers dynamically with the DNS server. For DHCP entry of DNS domain and server
Understanding Session Services
Before you use the information in this section to configure your ICA and RDP session
services, be sure you understand and use the following guidelines:
Note
Wyse thin clients running Windows XP Embedded also support virtual
desktop solutions as described in "Using VMware View Manger Services."
•
•
General Guidelines - The Thin-client session services are made available by servers
hosting Citrix ICA and Microsoft RDP software products.
ICA Guidelines - Independent Computing Architecture (ICA) is a three-tier,
server-based computing technology that separates the logic of an application from its
user interface. The ICA client software installed on the thin client allows the user to
interact with the application GUI, while all of the application processes are executed on
the server. For information on configuring ICA, refer to "Configuring ICA Session
Note
The ICA server must be licensed from Citrix Systems, Inc. You must
purchase enough client licenses to support the total concurrent thin client
load placed on the Citrix server farm. A failure to connect when all client
seats are occupied does not represent a failure of Wyse equipment. The ICA
client software is installed on the thin client.
•
RDP Guidelines - Remote Desktop Protocol (RDP) is a network protocol that allows a
thin client to communicate with the Terminal Service running on Windows 2000/2003/
Windows 2008 Server over the network. This protocol is based on the T.120 protocol
suite, an international standard multi-channel conferencing protocol. The thin client

Configuring ICA Session Services
Before you use the information in this section to configure your ICA session services, be
sure you have read "Understanding Session Services."
ICA session services can be made available on the network using either Windows 2000 or
2003 Server with Terminal Services and one of the following installed:
•
•
Citrix MetaFrame XP
Citrix Presentation Server
Use the instructions accompanying these products to install them and make sessions and
applications available to the thin clients sharing the server environment.
Note
If a Windows 2000 or 2003 Server or Citrix XenApp 5.0 with Windows Server
2008 is used, a Terminal Services Client Access License (TSCAL) server
must also reside somewhere accessible on the network. The server will grant
a temporary (120-day) license on an individual device basis. Beyond the
temporary (120-day) license, you must purchase TSCALs and install them on
the TSCAL server (you will not be able to make a connection without a
temporary or permanent license).
Configuring RDP Session Services
Before you use the information in this section to configure your RDP session services, be
sure you have read "Understanding Session Services."
RDP session services can be made available on the network to allow you to connect
remotely to a desktop computer running Microsoft Windows NT®, Windows 2000,
Windows 2003, and Windows XP Professional, and supported versions of Windows Vista,
or a server running Microsoft® Windows NT® Server 4.0, Terminal Server Edition,
Windows 2000 Server, Windows 2003 Server, and Windows 2008 Server. The Remote
Desktop Protocol allows a thin client to execute Windows applications within a Windows
GUI environment, even though they are actually being executed on the server.
Use the instructions accompanying these products to install them and make sessions and
applications available to the thin clients sharing the server environment.
Note
If a Windows 2000, 2003, or 2008 Server is used, a Terminal Services Client
Access License (TSCAL) server must also reside somewhere accessible on
the network. The server will grant a temporary (120-day) license on an
individual device basis. Beyond the temporary (120-day) license, you must
purchase TSCALs and install them on the TSCAL server (you will not be able
to make a connection without a temporary or permanent license).

Using VMware View Manger Services
®
VMware View Manager is a desktop management solution that enables system
administrators to provision desktops and control user access. Client software securely
connects users to centralized virtual desktops, back-end physical systems, or terminal
servers.
Note
Information on installing and configuring View Manager can be found on the
View Manager consists of the following major components:
•
View Connection Server—a software service that acts as a broker for client
connections by authenticating and then directing incoming remote desktop user
requests to the appropriate virtual desktop, physical desktop, or terminal server.
•
View Agent—a software service that is installed on all guest virtual machines, physical
systems, or terminal servers in order to allow them to be managed by View Manager.
The agent provides features such as RDP connection monitoring, virtual printing,
remote USB support, and single sign on.
•
•
View Client—a locally installed software application that communicates with View
Connection Server in order to allow users to connect to their desktops using Microsoft
Remote Desktop Protocol (RDP).
View Client with Offline Desktop (experimental)—a version of View Client that is
extended to support the Offline Desktop feature which allows users to download virtual
machines and use them on their local systems.
•
•
View Portal—a Web-based version of View Client supported by multiple operating
systems and browsers.
View Administrator—a Web application that allows View Manager administrators to
configure View Connection Server, deploy and manage desktops, control user
authentication, initiate and examine system events, and carry out analytical activities.
•
View Composer—a software service that is installed on the VirtualCenter server in
order to allow View Manager to rapidly deploy multiple linked clone desktops from a
single centralized base image.
Implementing View Client Support on Wyse Thin Clients
There are two ways to implement View Client support on Wyse thin clients running
Windows XP Embedded:
•
For the Windows XP Embedded WFR2 software release, View Client support is
provided as part of the XP Embedded image by including the XP Embedded View
Client component.
•
For the Windows XP Embedded WFR1 software release, View Client support can be
provided using a Wyse Device Manager (WDM) package to push the View Client to the
Wyse thin clients.
Note
The View Client requires 9 MB of space in the flash memory of the thin client.
Note
You must install Microsoft Remote Desktop Connection (Terminal Services
Client 6.0 or later) on the thin client before pushing the View Client WDM
package to a thin client with an XP Embedded SP2 WFR 1 image.

Getting Started
This chapter provides information to help you quickly get started using your thin client. It
describes basic thin client functions and provides instructions on setting up the thin client
for you and your users.
What Happens When You Turn on Your Thin Client
What you see, initially, when you turn on or reboot a thin client, depends on the method of
access to the enterprise intranet and how the network administrator has set up a user
account. In addition, with WDM software, a thin client can also be turned on remotely
using the Wake-On-LAN feature.
Logging On
administrators can configure a user account to logon automatically or require manual
logon with user credentials (User name, Password, and Domain) as described in
Note
Automatic logon to a User desktop is enabled on the thin client by default. To
log on as an administrator, log off the User desktop while holding down the
SHIFT key to display the Log On to Windows dialog box and use your
administrator credentials to log on (default User name and Password are
both Administrator).
Caution
For security purposes it is recommended that all default passwords be
changed on all thin clients (be sure to remember any new administrator
password, as you will not be able to log on as an administrator without it).
Only an administrator can log on to a thin client and change passwords by
using the CTRL+ALT+DEL key combination to open the Windows Security
window, clicking Change Password, and then using the Change Password
dialog box. Be sure to disable the File Based Write Filter before you change
a password on the thin client, and then enable the File Based Write Filter

Chapter 3
Automatic Logon
Automatic logon to a User desktop is enabled on the thin client by default. If you want to
log on as a different user while Auto Logon is enabled, log off the current desktop while
holding down the SHIFT key to display the Log On to Windows dialog box and use your
credentials to logon.
An administrator can log on and use Winlog (found in the administrator Control Panel) to
enable or disable Auto Logon, and to change the default User name, Password, and
Domain for a thin client. Only an administrator can change the Auto Logon properties of a
thin client.
Note
To save any configurations you make on a thin client to persist after a thin
client reboot (for example, Auto Logon properties), be sure to disable the File
Based Write Filter before your configurations to the thin client, and then
enable the File Based Write Filter after your configurations as described in
Manual Log-on
When automatic logon is not enabled, the Log On to Windows dialog box displays upon
thin client startup.
Use the following guidelines:
•
•
For a User account, the factory-default User name and Password are both User.
For an Administrator account, the factory-default User name and Password are both
Administrator.
Note
Passwords are case sensitive. User names are not case sensitive.
Configuring the Thin Client
While Users can make some configuration modifications to the thin client that are not lost
when you simply log off and on again (as the same or different user), only administrators
can modify thin client configurations to persist after a thin client reboot.
Use the following guidelines:
1. Log on as an administrator. If this is an initial logon to the thin client or you are logging
on to the thin client of a User, you must log off the User desktop while holding down the
SHIFT key to display the Log On to Windows dialog box and use your administrator
credentials to logon (default User name and Password are both Administrator).
Note
Automatic logon to a User desktop is enabled on the thin client by default. An
administrator can use Winlog (found in the administrator Control Panel) to
enable or disable Auto Logon and change the default User name, Password,
and Domain for the thin client. For example, as an administrator, you can use
Winlog to configure your thin client to start with the Log On to Windows
dialog box so that you can log on using your administrator credentials.

2. After logging on to the thin client, disable the File Based Write Filter by double-clicking
the FBWF Disable icon on the desktop (this will disable the filter and reboot the
system).
3. If automatic logon to a User desktop is enabled on the thin client, you must log off the
User desktop and log on as an administrator (log off the User desktop while holding
down the SHIFT key to display the Log On to Windows dialog box and use your
administrator credentials to log on).

on logging on as a different user, refer to "Logging On."
The following utilities are affected by logging off, restarting, and shutting down the thin
client:
•
File Based Write Filter cache - If you make changes to system configuration settings
and want them to persist after a reboot, you must flush the files of the File Based Write
Filter cache during the current system session. Otherwise, the new settings will be lost
when the thin client is shut down or restarted. The File Based Write Filter cache
contents are not lost when you simply log off and on again (as the same or different
user); that is, you can flush the files of the File Based Write Filter cache after the new
logon and still retain the changes. For instructions on flushing, refer to "Setting the File
Based Write Filter Controls." For general information about the File Based Write Filter,
Note
A User cannot flush the files of the File Based Write Filter cache; this is a

software to perform image updates and remote administration functions on devices
that have been shut down or are on standby. To use this feature, the thin client power
must remain on.
•
Thin Client Time - After power off, clock time will not be lost as long as the power
source remains on. Clock time will be lost if the power source is off and a battery is not
installed. The local time utility can be set to synchronize the thin client clock to a time
server automatically at a designated time, or manually.
Note
Correct time should be maintained as some applications require access to
local thin client time. The Date and Time Properties dialog box can be
opened by double-clicking the System time area in the taskbar or by

Preserving Wireless Connections
Windows XP Embedded WFR2 includes a tool called Regpersistence.exe which is
designed to configure wireless access in Write Filter Enable mode. When you configure
wireless access with this utility, the authentication credentials persist across reboots,
eliminating the need to re-authenticate each time the client systems are restarted. The
utility preserves the service set identifier (SSID) for wireless connections across
workgroup modes and domains. When Windows XP Embedded clients restart, they are
automatically connected to the desired wireless access point.
Windows XP Embedded clients can connect to wireless networks using the following
network authentication modes:
•
Open mode with WEP
Note
This authentication mode requires the network key to be entered while the
client is connected to the wireless network. Windows XP Embedded clients
are automatically connected to the wireless network after reboot.
•
•
•
•
•
•
Shared mode with WEP
WPA authentication with AES and TKIP
WPA-PSK with AES and TKIP data encryption.
WPA2 with AES and TKIP data encryption
WPA2-PSK with AES and TKIP data encryption.
PEAP authentication process
The session keys that are generated during the PEAP authentication process provide
keying material for the Wired Equivalent Privacy (WEP) encryption keys that encrypt the
data that is sent between wireless clients and wireless access points.
You can use PEAP with any of the following authentication methods for wireless
authentication (PEAP is not supported for use with EAP-MD5):
•
•
•
EAP-TLS, which uses certificates for server authentication and either certificates or
smart cards for user and client computer authentication.
EAP-MS-CHAP v2, which uses certificates for server authentication and credentials for
user authentication.
Non-Microsoft EAP authentication methods.

Note
PEAP is available as an authentication method for 802.11 wireless clients,
but it is not supported for virtual private network (VPN) clients or other
remote access clients. Therefore, you can configure PEAP as the
authentication method for a remote access policy only when you are using
Internet Authentication Service (IAS).
Using PEAP Fast Reconnect
When clients connect to an 802.11 wireless network, the authenticated session has an
expiration interval configured by the network administrator to limit the duration of
authenticated sessions. To avoid the requirement for authenticated clients to periodically
re-authenticate and resume a session, you can enable the fast reconnect option.
PEAP supports fast reconnect, as long as each wireless access point is configured as a
client of the same IAS (RADIUS) server. In addition, fast reconnect must be enabled on
both the wireless client and the RADIUS server.
When PEAP fast reconnect is enabled, after the initial PEAP authentication succeeds, the
client and the server cache TLS session keys. When users associate with a new wireless
access point, the client and the server use the cached keys to re-authenticate each other
until the cache has expired. Because the keys are cached, the RADIUS server can quickly
determine that the client connection is a reconnect. This reduces the delay in time
between an authentication request by a client and the response by the RADIUS server. It
also reduces resource requirements for the client and the server.
If the RADIUS server that cached the session keys is not used, full authentication is
required, and the user is again prompted for credentials or a PIN. This can occur in the
following situations:
•
The user associates with a new wireless access point that is configured as a client of a
different RADIUS server.
•
The user associates with the same wireless access point, but the wireless access point
forwards the authentication request to a different RADIUS server.
In both situations, after the initial authentication with the new RADIUS server succeeds,
the client caches the new TLS session keys. Clients can cache TLS session keys for
multiple RADIUS servers.
Using the Regpersistence Tool to Configure PEAP Wireless Connections
Use the following guidelines:
1. Image the Windows XP Embedded Client.
2. With the Write Filter enabled, configure a wireless connection.
3. When users log in, they are not prompted for wireless credentials.
Note
When you configure PEAP authentication with the Regpersistence tool, the
thin client must have a corresponding or relative user certificate and server
certificate for authentication. With the Regpersistence tool, the user name
and domain name are saved across reboots; the PEAP authentication
process prompts only for the password to prevent hackers from spoofing
user credentials while users are connected across a WAN.

Using the File Based Write Filter (FBWF)
The File Based Write Filter provides a secure environment for thin-client computing by
protecting the thin client from undesired flash memory writes (flash memory is where the
operating system and functional software components reside). By preventing excessive
flash write activity, the File Based Write Filter also extends the life of the thin client. It gives
the appearance of read-write access to the flash by employing a cache to intercept all
flash writes and returning success to the process that requested the I/O.
The intercepted flash writes stored in cache are available as long as the thin client
remains active but are lost when the thin client is restarted or switched off. To preserve
selected changes, the selected files of the cache can be transferred to the flash on
demand by using WDM software or manually by using Commit in the File Based Write
Filter Control dialog box; alternatively, if the files affected by the changes are not known,
the changes can be made after disabling the File Based Write Filter using the File Based
Write Filter Control dialog box, and then re-enabling the File Based Write Filter (see
"Setting the File Based Write Filter Controls"). The File Based Write Filter can be
controlled either through the command line (fbwfmgr) or by double-clicking the File Based
Write Filter icon in the Administrator system tray. The File Based Write Filter can flush
specified files to the flash from cache (only up to the point when the commit is performed;
if more writes are performed on the files that have been flushed, then these files must be
flushed/committed again if the additional changes also need to be preserved). The File
Based Write Filter can also be enabled/disabled through the command line or through the
File Based Write Filter Enable/Disable desktop icons. The status (enabled/disabled) of the
File Based Write Filter is displayed by the File Based Write Filter status icon in the system
tray (green indicates that the File Based Write Filter is enabled and red indicates that the
File Based Write Filter is disabled).

Caution
Contents of the File Based Write Filter cache should never be flushed if it is
eighty-percent or more full. The Administrator should periodically check the
status of the cache and restart the thin client if the cache is more than eighty
percent full.
Note
A Terminal Services Client Access License (TSCAL) is always preserved
regardless of File Based Write Filter state (enabled or disabled).
If you want to have other registry settings preserved regardless of File Based
Write Filter state, contact Wyse support for help as described in "Wyse

Changing Passwords with the File Based Write Filter
On Microsoft Windows NT-based computers and on Microsoft Windows 2000 or
2003-based computers, machine account passwords are regularly changed with the
domain controller for security purposes. By default, on Windows NT-based computers, the
machine account password automatically changes every seven days. On Windows 2000
or 2003-based computers, the machine account password automatically changes every
30 days.
The same password process is applicable for a thin client if the thin client is a member of
such a domain. With the File Based Write Filter enabled, a thin client will successfully
make this password change with the domain controller. However, since the File Based
Write Filter is enabled, the next time the thin client is booted it will not retain the new
password. In such cases, you can use the following options:
•
Disable the machine account password change on the thin client by setting the
DisablePasswordChangeregistry entry to a value of 1.
•
Disable the machine account password change in Windows NT 4.0 or in Windows
2000 or 2003, by setting the RefusePasswordChangeregistry entry to a value of 1
on all domain controllers in the domain instead of on all workstations. Wyse thin clients
will still attempt to change their passwords every 30 days, but the change will be
rejected by the server.
Note
On Windows NT 4.0 domain controllers, you must change the
RefusePasswordChangeregistry entry to a value of 1on all Backup
Domain Controllers (BDCs) in the domain before you make the change on
the Primary Domain Controller (PDC). Failure to follow this order will cause
event ID 5722 to be logged in the event log of the PDC.
If you set the RefusePasswordChangeregistry entry in the Windows 2000
or 2003 Domain Controller to a value of 1, the replication traffic will stop, but
not the thin client traffic. If you also set the DisablePasswordChange
registry entry to a value of 1in the thin client, both thin client and replication
traffic will stop.

Understanding the NetXClean Utility
NetXClean keeps extraneous information from being stored in flash memory. NetXClean is
a service that runs in the background. NetXClean clean-up is triggered by either a service
startup or a user log-off. It performs the clean-up invisibly and no user input is necessary.
NetXClean prevents garbage files from building up and filling the free space in the flash
(for example, if a flush of some files in the File Based Write Filter cache puts junk in flash
directories that must be kept clean). The NetXClean utility is particularly important when
multiple users have log-on rights to a thin client, as memory space can be quickly used by
locally stored profiles and temporary caching of information.
NetXClean TweakUI functions includes clearing:
•
•
•
•
•
•
•
Run history at log-on
Document history at log-on
Find Files history at log-on
Find Computer history at log-on
Internet Explorer history at log-on

NetXClean purges selected directories, files, and profiles. It uses a configuration file to
determine which directories and files to purge (and what not to purge). To select different
directories and files to purge, you must select them in the configuration file.
Caution
NetXClean purge selections are made by the manufacturer and should not
be changed without manufacturer supervision.
Regardless of the configuration file selections, NetXClean does not clean any of the
following directories or their parent directories:
•
•
•

Saving Files and Using Local Drives
Administrators need to know the following information about local drives and saving files.
Saving Files
Thin clients use an embedded operating system with a fixed amount of flash memory. It is
recommended that you save files you want to keep on a server rather than on a thin client.
Caution
Be careful of application settings that write to the C drive, which resides in
flash memory (in particular, those applications which by default write cache
files to the C drive on the local system). If you must write to a local drive,
change the application settings to use the Z drive. The default configuration
settings mentioned in "Managing Users and Groups with User Manager"
minimize writing to the C drive for factory-installed applications.
Note
For File Based Write Filter information, refer to "Using the File Based Write
Drive Z
Drive Z is the on-board volatile memory (Ms-ramdrive) of the thin client. It is
recommended that you do not use this drive to save data that you want to retain.
For Ramdisk configuration information, refer to "Setting Ramdisk Size."
For information about using the Z drive with roaming profiles, refer to "Participating in
Drive C and Flash
Drive C is the on-board non-volatile flash memory. It is recommended that you avoid
writing to drive C. Writing to drive C reduces the size of the flash. If the flash size is
reduced to under 3 MB, the thin client will become unstable.
Caution
It is highly recommended that 3 MB of flash memory be left unused. If the
free flash memory size is reduced to 2 MB, the thin client image will be
irreparably damaged and it will be necessary for you to contact an authorized
service center to repair the thin client.
The File Based Write Filter (if enabled) protects the flash from damage and presents an
error message if the cache is overwritten. However, if this message occurs you will be
unable to flush files of the File Based Write Filter cache and any thin client configuration
changes still in cache will be lost. For information on the role of NetXClean in keeping the
flash memory clean, refer to "Understanding the NetXClean Utility."
Items that are written to the File Based Write Filter cache (or directly to the flash if the File
Based Write Filter is disabled) during normal operations include:
•
•
•
Favorites
Created connections
Delete/edit connections

Mapping Network Drives
Users and administrators can map network drives. However, to retain the mappings after
the thin client is restarted, you must complete the following:
•
•
Select the Reconnect at logon check box.
Flush the files of the File Based Write Filter cache during the current system session.
Since a User log-on account cannot flush the files of the File Based Write Filter cache,
the mappings can be retained by logging off the user account (do not shut down or
restart the system), logging back on using an administrator account, and then flushing
the files of the cache.
Note
A remote home directory can also be assigned by using a user manager
utility or by other means known to an administrator.
Participating in Domains
You can participate in domains by joining the thin client to a domain or by using roaming
profiles.
Joining a Domain
As an administrator you can join a thin client to a domain through the Computer Name
Changes dialog box (Start | Control Panel | System | Computer Name | Change).
Caution
Exercise caution when joining the thin client to a domain as the profile
downloaded at log-on could overflow the cache or flash memory.
When joining the thin client to a domain, the File Based Write Filter should be disabled so
that the domain information can be permanently stored on the thin client. The File Based
Write Filter should remain disabled through the next boot as information is written to the
thin client on the boot after joining the domain. This is especially important when joining an
Active Directory domain. For instructions on disabling and enabling the File Based Write
Filter, refer to "Using the File Based Write Filter (FBWF)."
To make the domain changes permanent, complete the following:
1. Disable the File Based Write Filter.
2. Join the domain.
3. Reboot the thin client.
4. Enable the File Based Write Filter.
5. Reboot the thin client.
Note
If you use the FBWF Enable icon to enable the File Based Write Filter, the
second reboot will happen automatically.
By default, the NetXClean utility will purge all but specifically selected profiles
on the system when the thin client starts up or when the user logs off. For
information on how to ensure a new profile is not purged by the NetXClean
utility, refer to "Understanding the NetXClean Utility."

Chapter 5
Using Roaming Profiles
You can participate in domains by writing roaming profiles to the C drive. The profiles must
be limited in size and will not be retained when the thin client is restarted.
Note
For successful downloading and proper functioning, there must be sufficient
flash space available for roaming profiles. In some cases it may be
necessary to remove software components to free space for roaming
profiles.
Using the WinPing Diagnostic Utility
WinPing is used to launch the Windows PING (Packet InterNet Groper) diagnostic utility
and view the results from pinging. To open the WinPing window, click Start | Run, enter
WinPingin the text box, and click OK.
Figure 34 WinPing
WinPing is a diagnostic tool that sends an echo request to a network host. The host
parameter is either a valid host name or an IP address. If the host is operational and on
the network, it responds to the echo request. The default is to send 5 echo requests and
then stop if no response is detected. WinPing sends one echo request per second,
calculates round trip times and packet loss statistics, and displays a brief summary upon
completion.
WinPing is used to:
•
•
•
•
Determine the status of the network and various hosts.
Track and isolate hardware and software problems.
Test, measure, and manage networks.
Determine the IP address of a host if only the host name is known.

Managing Users and Groups with User Manager
The User Manager allows administrators to create new user accounts and configure user
profiles. It also allows administrators to create new groups and determine group
membership. By default, a new user is only a member of the Users group and is not
locked down. As the Administrator, you must select the attributes and profile settings for a
new user.
Caution
By default, all application settings are set to cache to C drive. It is highly
recommended that you cache to the Ramdisk Z drive (as is pre-set in the
User and Administrator accounts) to avoid overflowing the File Based Write
Filter cache.
Creating New User Accounts
Only administrators can create new user accounts locally or remotely through VNC.
However, due to local flash/disk space constraints, the number of additional users should
be kept to a minimum.
Caution
Be sure to flush the files of the File Based Write Filter cache during the
current system session in which a new account is created.
Use the following guidelines:
1. Log-in as an administrator and open the User Manager (Start | Control Panel |
Administrative Tools | User Manager).
2. Click the Users folder, click Action in the menu bar, and then select New User to open
the New User dialog box.
3. Enter the user information and credentials, select the attributes you want for the user,
and then click Create (you can continue to create as many users as you want).

Configuring User Profiles
Only administrators can select the profile settings for a user.
Caution
Because of the limited size of the flash memory, it is strongly recommended
that other applications available to new and existing users be configured to
prevent writing to the local file system. For the same reason, it is also
recommended that extreme care be exercised when changing configuration
settings of the factory-installed applications.
Use the following guidelines (example of adding a user to the Administrator group):
Caution
Be sure to flush the files of the File Based Write Filter cache during the
current system session in which an account is modified.
1. Log-in as an administrator and open the User Manager (Start | Control Panel |
Administrative Tools | User Manager).
2. Click the Users folder, double-click on a user to open the User Properties dialog box,

Using Windows Server Update Services (WSUS) on a Thin Client
This section describes how to use WSUS to automatically deploy software updates on a
Wyse thin client running Windows XP Embedded. Before using WSUS to deploy software
updates, the server must be properly configured for WSUS.
Configuring the Thin Client for WSUS
The default Windows XP Embedded installation on a thin client does not allow users who
are not administrators to receive update notifications. To check the update notification
status on a thin client, do the following:
1. On the thin client, click Start | Run. In the Run box, enter gpedit.msc.
2. Navigate to Computer Configuration, then Windows Components, then Windows
Update. If the “Allow non-administrators to receive update notifications” option or GPO
does not appear, you need to modify the wuau.adm file on the thin client.
To modify the wuau.adm file to allow non-administrators to receive update notifications,
follow these steps:
1. Disable the Write Filter on the thin client.
2. Copy the wuau.adm file from the Windows 2003 server or from the Windows XP
operating system into the c:\windows\inf folder.
3. Enable the Write Filter on the client.
Note
The thin client must be part of a group or GPO configured on the server that
distributes the updates.

Chapter 6
Automatic Software Updates on Wyse Thin Clients Using WSUS
This section describes three ways to automatically deploy software updates on thin clients
using WSUS:
•
•
•
Using WSUS on the Wyse Thin Client in Standalone Mode
You can configure WSUS on the Wyse thin client to automatically check for and install new
software updates. By default, the client checks for updates every 22 hours, but you can
configure a shorter interval (the frequency limit is one hour). When an update is available,
the client downloads the update, using only available bandwidth, without user notification,
since there is no impact to user activity (however, you can configure user notification, if
desired).
Once the software is downloaded to the client, installation can occur according to the
policy configured using gpedit.msc. When configuring policy, it is important to consider the
impact of installations on the user. All client updates require reboot of the thin client.
Prerequisites
Before any software updates can be deployed via WSUS, you must:
•
•
Install WSUS Server v. 2.0 or WSUS Server v.3.0 on the server.
Configure communication between the thin client and the server.
To configure WSUS using the GUI:
1. Right-click the My computer icon and select Properties from the context menu.
2. Click the services.msc tab to display the Automatic Update Component and the
corresponding service.
3. Configure the Group Policy to communicate with the WSUS intranet server.
4. When the Windows XP Embedded client contacts the WSUS server, notification of
pending software updates appears on the taskbar.
5. To install the software updates, run the scripts to disable the Write Filter before the
installation, and enable it after installation, as described in the "About VB Scripts"
section.
Note
You must disable the Write Filter before you can install the required updates.
When the Write Filter is enabled, the thin client can save the update files until
the next client reboot. Upon reboot, the update files are deleted.
To configure WSUS using the command line interface:
1. From the Start menu, choose Run to display the command prompt.
2. At the command prompt, type wuauclt.exe.
3. Run the executable file and configure the Group Policy for the client to communicate
with the WSUS intranet server.
4. To install the software updates, run a script to disable the Write Filter before the
installation, and enable it after installation, as described in the "About VB Scripts"
section.

Troubleshooting WSUS in Standalone Mode
WSUS provides a log for troubleshooting issues related to software updates. This log is
located on the thin client, in the directory: C:\windows\windowsupdate log. This log
displays all communications between the client and the server. You can use PERFMON to
monitor memory allocation for the WSUS client web services component and WSUS
server web services component of the update log.
Note
Alternatively, you can use a network monitoring or packet sniffing tool to
monitor the traffic between the client and the server.

Configuring WSUS for Automatic Software Updates Using SMS
You can configure WSUS to use the SMS server to perform automatic software updates in
either a Workgroup environment or using Active Directory.
Prerequisites
Before any software updates can be deployed via WSUS, you must:
•
•
•
Install SMS 2003 or SMS 2007 on the server and the thin client.
Install WSUS Server v. 2.0 or WSUS Server v.3.0 on the server.
Configure the thin client for WSUS, following the procedure in the "Configuring the Thin
Client for WSUS" section.
To use WSUS along with SMS to perform automatic software updates on a thin client:
Push the required script (pre-script) from the SMS server to the clients connected to the
SMS server. The script must be configured to:
1. Disable the Write Filter.
2. Initiate the download and installation of the appropriate updates on the thin clients.
3. Enable the Write Filter.
About VB Scripts
Software distribution via SMS requires two Write Filter actions on the XP Embedded thin
clients: one action disables the Write Filter before the application deployment, and the
other action enables the Write Filter following the application deployment. There is one VB
script to perform each action.
Note
The VB scripts run on the thin client without any prompt messages.
The Disable_ewf_fbwf.vbs script disables the EWF and FBWF Write Filters and restarts
the thin client within 60 seconds. Following the restart, the Write Filter is disabled.
After this script is executed, you can deploy an application or patch to the thin client.
Following the software deployment, run the Enable_ewf_fbwf.vbs script to enable the
EWF and FBWF Write Filters and restart the thin client within 60 seconds. Following the
restart, the Write Filter is enabled.
Note
If WSUS 3.0 is installed on the server, you can monitor the progress of the
software updates on the thin clients and push the script to re-enable the
Write Filter after the update is complete.
Troubleshooting WSUS Used with SMS
available for use with SMS.
In addition, you can use the SMS server log to identify the package status and the WSUS
client log to troubleshoot update status issues.

enables the Write Filter to run on the thin client.
Troubleshooting WSUS with WDM
You can use the steps described in the “Troubleshooting WSUS in Standalone Mode”
section to troubleshoot the issues related to the software update on clients and on the
WDM server by analyzing the relevant logs present on both the client and the server:
•
•
•
•
WindowsUpdate.log file—provides statistics
PERFMON counters—help administrators to check the utilization
Netmon or Ethereal trace—shows data flow
Event logs—display the events, including any failures
User Instructions on the First Boot Process After Loading a Standard
Image (v2.2 or Earlier Only)
If you are running XP Embedded version 2.2 or earlier, you must follow these important
instructions when imaging the Wyse thin clients with the standard XP Embedded image
downloaded from the Wyse Web site.
Note
When performing a mass distribution of a custom device image that has
been created with Rapport, certain devices will require unique preparation
prior to image creation and distribution. Please contact the device
manufacturer for more detailed information.

Action: If this System Settings Change message appears, click No. Do not interrupt the
thin client while it is automatically running through configuration and reboot.
Using WinVNC to Shadow a Thin Client
Administrators Only - WinVNC Server is installed locally on the thin client. It allows a thin
client to be operated/monitored (shadowed) from a remote machine on which VNC Viewer
is installed. This allows a remote administrator to configure or reset a thin client from a
remote location rather than making a personal appearance at the thin client site. VNC is
intended primarily for support and troubleshooting purposes.
VNC Server starts automatically as a service at thin client startup. The service can also be
stopped and started by using the Services window (opened by clicking Start | Control
Panel | Administrative Tools | Services).
Note
If you want to permanently save the state of the service, be sure to flush the
files of the File Based Write Filter during the current system session.
Setting VNC Server Properties
To open the WinVNC: Current User Properties dialog box, click Start | Programs |
WinVNC Current User Properties, or double-click the WinVNC icon in the system tray of
the Administrator taskbar. For information on configuring VNC, refer to the VNC
Caution
The default password in this dialog box is Wyse. For security, it is highly
recommended that the password be changed (to one known only by the
Administrator) immediately upon receipt of the thin client.

System Administration
67
Figure 40 WinVNC: Current User Properties
Before a remote machine (on which VNC Viewer is installed) can access a thin client:
•
The IP address (or valid DNS name) of the thin client that is to be operated/monitored
must be known by the remote administrator/user. This IP address can be obtained from
the Details area (Local Area Connection) of the Network Connections dialog box
(accessed by clicking Start | Control Panel | Network Connections, clicking the
Local Area Connection icon and scrolling down to the Details area in the left pane).
Note
To obtain the IP address of an administrator thin client, hover the mouse
arrow over the VNC icon in the system tray of the Administrator taskbar.
•
A password for an administrator to use must be entered into the WinVNC: Current
User Properties dialog box.
Setting VNC Viewer Options
VNC Viewer software is included as a component of WDM software and must be installed
on the remote (shadowing) machine. An administrator/user of the remote machine must
know the IP address/name and the password of a the thin client that is to be operated/
monitored.
If a UNIX, Linux, Solaris, or HP-UX machine is to be used to remotely access your thin
client, the appropriate VNC Viewer software must be obtained and installed on the remote
machine. For information on VNC software, refer to the VNC Web site at:
An administrator/user of the remote (shadowing) machine can log-on to a thin client by
completing the following:
1. Double-click the VNC Viewer icon to open the Connection Details dialog box.

Chapter 6
2. (Optional) You can configure advanced VNC connection options using the Connection
Options dialog box. For example, if the network is slow, click Options to open the
Connection Options dialog box, select the Restrict Pixels to 8-bit check box in the
Display area (reduces color depth for better transmission speed), and then click OK to
return to the Connection Details dialog box.
Figure 42 VNC Connection Options
Note
The VNC Connection Options dialog box varies for different VNC software
releases.
Configure using the following general guidelines:
•
Preferred encoding options - Normally the VNC Viewer requests CopyRect,
Hextile, CoRRE and RRE in that order. The selection alters this behavior by
specifying the encoding method to be used before any of the others are tried.
•
•
Allow CopyRect encoding - When selected, VNC Viewer informs the VNC Server
it can cope with CopyRect encoding.
Request shared session - When you make a connection to a VNC Server, all
other existing connections are normally closed. This option requests that they be
left open, allowing you to share the desktop with someone already using it.
•
Deiconify on Bell - Often a beep will sound because you are being notified of
something such as e-mail arriving or a compilation finishing. This selection causes
a minimized VNC Viewer to be restored when the bell character (escape sequence)
is received.
•
•
Disable clipboard transfer - Clipboard changes caused by cutting or copying at
either the VNC Viewer or the VNC Server are normally transferred to the other end.
This option disables clipboard transfers.
Emulate 3 Buttons (with 2-button click) - When selected, users with a two-button
mouse can emulate a middle button by clicking both buttons at once.
•
•
Swap mouse buttons 2 and 3 - Generally selected by left-handed persons.
Restrict pixels to 8-bit (for slow networks) - When selected, reduces color depth
for better transmission speed.
•
•
View only (inputs ignored) - Select this option if you only want to monitor the
desktop of the remote thin client but do not want to operate it using the keyboard
and mouse.
Full-screen mode - Causes the connection to start in full-screen mode.
