•
The CIM data model abstracts and describes all elements in a network
environment. The CIM schema provides the actual data model
descriptions and arranges the network into a series of managed objects,
all interrelated and broadly classified.
•
The CIM schema is defined by the Managed Object Format (MOF) file,
which provides a standardized model for describing management
information between clients in a management system. The MOF file is not
bound to a particular implementation, and it allows the interchange of
management information between many different management systems
and clients.
WMI is Microsoft's implementation of CIM instrumentation. WMI supports
CIM and Microsoft-specific CIM extensions. The WMI management
infrastructure also includes the CIM Object Manager (CIMOM), which is
the interface and manipulation point for CIM objects and information.
It acts as a facilitator in gathering information and manipulating object
properties. OMCI provides data to WMI, which is the common interface
to WMI management applications. For more information, see "Windows
Management Instrumentation."
Data Sources Used by OMCI
OMCI contains the underlying driver set that collects system information from a
number of different sources on the client system, including the BIOS, CMOS,
System Management BIOS (SMBIOS), System Management Interface (SMI),
operating system, Application Programming Interfaces (APIs), Dynamic Link
Libraries (DLLs), and registry settings. OMCI exposes that information through
the CIMOM interface of the WMI stack and enables IT administrators to
remotely collect asset information, modify CMOS settings, receive proactive
notification of potential fault conditions, and be alerted to potential security
breaches.
8
Introduction
OMCI uses a variety of data sources resident on the client system which
includes:
•
•
•
•
•
•
Microsoft Win32 WMI providers
SMBIOS
Device drivers
Operating system registry
Operating system Application Programming Interfaces (APIs)
WMI repository
OMCI Architecture
The OMCI architecture is based on a layered model that is tightly integrated
with the Microsoft WMI stack as shown in Figure 1-1.
•
WMI application layer — Consists of management applications such as
Dell Client Manager, Dell OpenManage Client Administrator (OMCA),
and other standards-based management tools and WMI applications
such as Microsoft SMS, LANDesk, and so on. This layer is not a part of
OMCI and the applications are consumers of systems management data
supplied from the client by OMCI. These applications request client
information and receive client alerts through the CIMOM.
•
Dell WMI provider — Lies beneath the CIMOM and contains two CIM
providers which register with the CIMOM. When the CIMOM receives
a request for information, it routes the request to the appropriate
provider. Both Dell and Microsoft providers exist in this layer, and they
provide information on system devices. The providers send management
application requests from the CIMOM to the data router.
•
•
Data router — Collects information from system components in the
data provider layer and passes the information up to the Dell WMI
provider layer, which then presents it to the CIMOM.
Data provider — Provides data to the data router. When it receives a
request from the data router, the data provider queries the client system's
hardware, drivers, and operating system to determine the available
instrumentation. It then applies all platform and customer overrides to the
data before returning it to the data router.
Introduction
9
For example, a management console in the WMI application layer requests
the available free space on the client system hard drive. The WMI application
layer makes the request over the network to the CIMOM (in the Dell WMI
provider layer) on the client system. The CIMOM routes the request to the
appropriate WMI provider, which, in turn, routes the request through the
data router layer to the disk data provider in the data provider layer. The
information is then returned (through the same path in reverse) to the
management console.
NOTE: OMCI 7.6 and later versions will not be supported by Dell OpenManage
IT Assistant (ITA) 8.x.

Remote Boot Device Select
WMI Security
Event Reporting
Remote Shutdown
Remote Wake-Up Configurability
WfM Version 2.0 Compliance
CIM 2.6 Schema Support
CIM is a standard that describes management data that can be used by many
management application programs. OMCI conforms to the CIM 2.6 Schema,
and includes two WMI providers: Dell WMI Indication Provider/Polling
Agent and Dell WMI Instance/Method Provider.
Dell LegacySelect 2.0 Support
LegacySelect allows a network administrator to selectively enable or disable
legacy components in a Dell system. It is a BIOS-level interface which lets
you control the level of legacy technology your varied workgroups require.
LegacySelect 2.0 supports the ability to enable or disable ports, including
USB, PCI slots, and disk drives.
The LegacySelect 2.0 specification supports the following components:
•
•
•
•
•
•
•
•
Serial port
Parallel port
Diskette drive controller
Personal System/2 (PS/2) mouse port
Integrated audio controller
Integrated network interface controller (NIC)
Universal Serial Bus (USB) controller
Peripheral Component Interconnect (PCI) slot
Introduction
11
A network administrator can change the settings of these components either
through the computer's system setup or by using a WMI management
application.
NOTICE: Changing LegacySelect attributes such as Integrated Drive Electronics
(IDE) Controller may cause a computer system to become unusable. If this occurs,
enter system setup on the client system and change the applicable setting.
Remote Boot Device Select
Remote Boot Device Select allows a network administrator to remotely
configure the order of devices from which the system attempts to boot.
It consists of two groups: Hard Disk Drive Sequence and Boot Device
Sequence. Hard Disk Drive Sequence is used to set the order of the hard
drives, and Boot Device Sequence is used to set the order of the type of boot
device, such as hard drive, NIC, CD-ROM drive, and diskette drive.
WMI Security
WMI provides for user authentication before granting access to CIM data
and methods. Access privileges are enforced by distributed component object
model (DCOM) security and the CIMOM.
Event Reporting
OMCI detects events on Dell systems and can alert the local user and
network administrator to potential failures, configuration changes, and
chassis intrusions. These events are displayed by a system management
application program such as IT Assistant.
OMCI allows you to set polling intervals for a client Dell computer's Self-
Monitoring Analysis and Reporting Technology (SMART) hard drive,
environmental monitors, chassis intrusion, hard drive threshold, or error
checking and correction (ECC) code single-bit memory error events.
A polling interval defines how often the instrumentation code checks the
device status. Polling intervals are important because they determine how
often OMCI checks for an alert state on the system, and therefore, how often
it generates an alert. If the polling intervals are set too high, you may miss an
alert. For example, systems that support a thermal probe also have a
maximum temperature where the system will shut down regardless of other
12
Introduction
processes that may be running. If the temperature increases too quickly and
OMCI does not poll the system in time, it will not generate a shutdown
message and the system will not shut down cleanly.
OMCI also contains a start delay for the polling intervals. This determines how
long after the operating system loads, OMCI starts checking for the alert status.
An alert may be missed if the start delay is set too high.
For instructions on setting polling intervals and enabling or disabling alerts
for these devices, see the documentation for your systems management
application program.
Remote Shutdown
OMCI supports remote system shutdown and restart.
Remote Wake-Up Configurability
OMCI supports configuration of remote wake-up settings. Remote wake-up is
a function of the client system and NIC.
WfM Version 2.0 Compliance
®
OMCI is compliant with the Intel Wired for Management (WfM) 2.0
standard. For more information on this standard and its specifications, see the
Intel website at www.intel.com.
What's New
The following are new updates to OMCI 7.6:
•
•
Support for new platforms: Support for new Dell Latitude
™,

Introduction
Client Instrumentation
Dell OpenManage Client Instrumentation (OMCI) can be installed locally
using the OMCI installation wizard, or remotely through a silent or
administrative installation.
Local Installation: The OMCI installation wizard allows you to install the
complete package or to do a custom installation of specific components
required for a particular environment. OMCI can also be modified, repaired,
or removed through the Add/Remove Programs dialog in the
®
®
Microsoft Windows operating system environment.
Silent Installation: OMCI provides a series of command-line switches for
silent installation. This allows you to remotely install the product using an
electronic software distribution tool with no end-user interaction.
Administrative Installation: You can use a server image to deploy OMCI to
client computers on a network by using a login script, Windows system
policies, or other methods.
A default OMCI uninstallation does not uninstall the driver files and the
associated DLL files and they remain on the system. A command line
property (UNINSTALL_DRIVER=1) has to be specified on the command
line for a command line product uninstall, which will uninstall OMCI as well
as the driver files.
For example, the following command uninstalls the product as well as the
driver files:
msiexec.exe /X{09ADA709-10D2-4C38-807C-7B84F696F6CE}
/qn UNINSTALL_DRIVER=1
NOTE: To install OMCI, you must have administrative rights on the client system.
This means that you must be authenticated on the client system as a user who is a
member of the Administrators group, typically the Administrator. The target system
must be a Dell system with SMBIOS version 2.3 or later. Otherwise, the OMCI 7.6
installer will exit without installing OMCI.
Installing Dell™ OpenManage™ Client Instrumentation17
NOTE: You cannot upgrade from OMCI 6.x to OMCI 7.6 using the OMCI 7.6 installer
if the target system has OMCI 6.x on it. Ensure that you uninstall OMCI 6.x before
installing OMCI 7.6. OMCI version 7.2 and later can be installed only on Dell systems
running the Windows operating systems listed in the "Supported Operating
Systems" section.
NOTE: You can upgrade to OMCI 7.6 from OMCI versions 7.4 A00, 7.5 A00, 7.5 A01,
7.5 A02, and 7.5 A03. If the upgrade path includes an operating system upgrade to
Windows Vista, then you must upgrade OMCI to 7.6 first, and then upgrade the
operating system to Windows Vista; vice versa is not supported.
NOTE: Separate installation programs exist for Windows 32- and 64-bit Edition
operating systems, and are available for download from the Dell Support website at
support.dell.com.
User Account Control in Windows Vista
In previous versions of Windows, user accounts were often members of the
local Administrators group and had administrator privileges. Members of the
local Administrators group could install, update, and run software since an
administrator account had system-wide access. When a user was added to the
local Administrators group, that user was automatically granted every
Windows privilege because administrator privileges provide access to all
operating system resources. User accounts with administrator privileges posed
a security risk by providing access to operating system resources that can be
exploited by malicious software (or malware).
In Windows Vista, there are two types of user accounts: standard user
accounts and administrator accounts. Additionally, Windows Vista provides
User Account Control (UAC) to improve system security by limiting the
operating system access available to standard user accounts and requiring
members of the Administrators group (except the Administrator account) to
acknowledge the elevation of privileges when performing certain actions. The
primary difference between a standard user and an administrator in Windows
Vista is the level of access the user has over core, protected areas of the
computer. With UAC enabled, Windows Vista either prompts for consent to
elevate privileges (in the case of a user in the Administrators group) or for
administrator credentials to elevate privileges (in the case of all other users)
before launching a program or task that requires full administrator access.
UAC prompts members in the Administrators group (except the
Administrator account) to click Continue, if they need to elevate privileges,
18
Installing Dell™ OpenManage™ Client Instrumentation
or to click Cancel when performing functions that may entail a security risk.
With UAC, you can run most applications, components and processes with a
limited privilege, but have elevation potential for specific administrative tasks
and application functions.
During OMCI installation or uninstallation, depending upon the access level
of the user, Windows Vista prompts the user for administrator authorization.
You must provide the administrator password for installing or uninstalling
OMCI if you have standard account privileges, since OMCI installation and
uninstallation need administrative privileges. Even when you are logged in as
a member of the Administrators group (except the Administrator account),
UAC requires you to give your consent to allow the installation or
uninstallation.
NOTE: Since the user experience is configurable with the Security Policy Manager
snap-in (secpol.msc) and with Group Policy, there are multiple UAC user
experiences. The configuration choices made in your environment will affect the
prompts and dialogs seen by standard users, administrators, or both. The specific
behavior of the UAC elevation prompt is dependent upon the Security Policy setting.

Silent Installation
Installing the Client in the Silent Mode
In the silent mode (no dialog boxes appear), you can perform complete and
custom installations.
NOTE: When typing commands, enter spaces exactly as shown in the examples in
this section.
Performing a Complete Installation in Silent Mode
To perform a silent unattended installation of OMCI with all components in
the default directory:
setup.exe /s /v/qn
where setup.exe is the installation executable file for OMCI.
To specify the installation language use the /L<language ID>option,
where <language ID>is 1031 (German), 1033 (English), 1034 (Spanish),
1041 (Japanese), 1036 (French), or 2052 (Simplified Chinese). If the
installation language is not specified, the installer selects the default
operating system language, or to English if OMCI does not support the
operating system language.
For example, the following command line installs the French version in silent
mode:
setup.exe /s /L1036 /v/qn
Performing a Custom Installation in Silent Mode
To specify a custom installation directory, modify the command line as
follows:
setup.exe /s /v"/qn INSTALLDIR=<destination>"
where <destination>is the custom directory and INSTALLDIRmust be
in uppercase.
For example, the following command line installs OMCI with all components
in silent mode under the directory c:\destination:
setup.exe /s /v"/qn INSTALLDIR=c:\destination"

21
Upgrading the Client in Silent Mode
To upgrade from one version of OMCI 7.x to a later version of OMCI 7.x,
execute the following command:
setup.exe /s /v"/qn REINSTALLMODE=voums REINSTALL=
ALL"
A reboot might be required for the upgrade. To suppress it, modify the
command line as follows:
setup.exe /s /v"/qn REINSTALLMODE=voums REINSTALL=ALL
REBOOT=REALLYSUPPRESS"
Uninstalling the Client in Silent Mode
You can uninstall the client instrumentation in silent mode either using or
without using the installation program.
To uninstall the client instrumentation without the installation program in
silent mode, run one of the following commands:
For all 32-bit Windows installations:
msiexec.exe /X{73F1BDB7-11E1-11D5-9DC6-00C04F2FC33B}
/qn
For all 64-bit Windows installations:
msiexec.exe /X{09ADA709-10D2-4C38-807C-7B84F696F6CE}
/qn
To uninstall the client instrumentation with the installation program in silent
mode, run the following command from the directory containing the
installation program:
setup.exe /s /x /v/qn

Windows Management
Instrumentation
WMI Overview
®
®
Microsoft Windows Management Instrumentation (WMI) is Microsoft’s
implementation of the Web-Based Enterprise Management (WBEM) effort.
It is implemented on Microsoft Windows platforms.
There are two components to WMI. In the Dell™ OpenManage™ Client
Instrumentation (OMCI) architecture (see Figure 1-1), both the components
are represented by the Microsoft WMI Object Manager. The first component
is the Common Information Model (CIM) Object Manager (CIMOM), which
is the interface and manipulation point for CIM objects and information.
It acts as a facilitator in gathering information and manipulating object
properties. Microsoft has implemented this component as the Windows
management (winmgmt) service. The CIMOM is a software middle layer that
mediates interactions between high-level management applications and the
lower levels of instrumentation, such as OMCI and other providers. The
CIMOM ensures that data supplied by providers is presented to management
applications in a uniform and provider-independent way. The CIMOM does
this, in part, by using the Component Object Model (COM) Application
Programming Interface (API) for communication with providers and
management applications.
The second WMI component is the repository. The repository is a binary file
where the CIMOM stores management data. Such data includes information
from the compiled Managed Object Format (MOF) file(s), including the
CIM class definitions, properties, qualifiers, and hierarchical relationships.
Instance data, as it becomes available, is also stored here.
WMI Security
WMI provides for user authentication before granting access to CIM data
and methods. Access privileges are enforced by Distributed Component
Object Model (DCOM) security and the CIMOM. Access, whether full
Windows Management Instrumentation
25
or limited, can be granted to users on per-namespace basis. There is no
implementation of class or property-level security. By default, users that are
members of the administrators group have full local and remote access to
WMI.
WMI security can be configured using the WMI Control available in the
Computer Management console under the Services and Applications
section. Right-click WMI Control, and then click Properties. You can
configure namespace-specific security from the Security tab. WMI Control
can also be executed from the Start menu or the command prompt by
running wmimgmt.msc.
NOTE: To connect remotely to WMI services, you must have administrative rights
for both the local and the remote systems.
NOTE: In Microsoft Windows XP, the default authentication level is changed from
CONNECT to PACKET level. This results in a backward compatibility problem with
Windows 2000. Systems running Windows 2000 need to have Service Pack 2
installed to be able to connect to WMI on systems running Windows XP.
Retrieving Dell Information With SMS 2.0
Due to inherent limitations, Microsoft Systems Management Server (SMS)
2.0 can only retrieve information from the root\cimv2 namespace. OMCI
provides information in the root\dellomci namespace. However, to make
certain key attributes available to SMS, OMCI duplicates them in the
root\cimv2 namespace. For Dell systems running OMCI, you can import the
following system attributes into SMS 2.0:
•
•
•
•
•
•
•
•
Service tag
Asset tag
System vendor
System description
Basic input/output (BIOS) revision
BIOS date
Processor type
Processor speed
26
Windows Management Instrumentation
To retrieve these Dell attributes, edit the sms_def.mof file available on the
SMS server in the sms\inboxes\clifiles.src\hinv directory. Add the following
lines to the end of the sms_def.mof file:
[SMS_Report(TRUE),
SMS_Group_Name("Dell Summary"),
ResID(7000),ResDLL("dellwmi.dll"),

WMI Scripts
WMI provides a scripting interface. Using VBScript or JScript, you can write
scripts that connect to WMI services locally or remotely, retrieve information,
or execute methods. Because OMCI is implemented through WMI, most
OMCI tasks can be scripted. This section provides sample VBScript scripts as
examples only.
NOTE: To connect remotely to WMI services, you must have administrative rights
for both the local and the remote systems.
28
Windows Management Instrumentation
The following text files contain sample scripts. To execute any of the scripts,
save the script with a .vbs extension. At the command prompt, type
parameters. If you do not specify any parameters, the usage for the script will
be printed out.
NOTICE: The sample scripts are provided as examples only, and have not been

Alerts
Overview
Alerts are generated when a system’s state of interest changes. There are two
basic types of alerting: local alerting to the current computer user and remote
alerting to a management application. Dell™ OpenManage™ Client
Instrumentation (OMCI) handles both types of alerting.
The Distributed Management Task Force (DMTF) has released the Alert
Standard Format (ASF), which defines alerting and remote control interfaces
that enable management of networked systems when their operating system
is absent. This includes a networked computer that has an inactive or
inoperable operating system or that is in a low-power system sleep state.
The ASF specification is available at www.dmtf.org. ASF documentation is
provided with Dell systems that support ASF.
ASF handles remote alerting for environmental events, which are detected by
sensors, such as temperature, electrical, and fan probes, and chassis intrusion
sensors. ASF also handles additional alerting in the operating-system-absent
environment. By default, OMCI handles remote alerting for all events.
ASF 2.0 adds important security measures to the ASF standard, which defines
alerting and remote control interfaces to proactively manage networked devices
when their operating system is absent. The first industry specification for
operating system absent management, ASF allows a network administrator to be
alerted to failures of specific components within a networked device, thereby
minimizing on-site maintenance while maximizing remote visibility of and
access to local systems. Without ASF, operating system absent problems require
manual intervention to force a reboot of the system.
There are three settings in the system BIOS that OMCI allows for
configuration:
•
•
•
Off
Alert Only
On Alerts and remote control are turned on.
—
All ASF 2.0 features are turned off.
—
ASF 2.0 alert is the only feature that is turned on.
—
Alerts
31
The system network interface card (NIC) and basic input/output system
(BIOS) support ASF 2.0. If the BIOS allows for any ASF 2.0 configuration,
®
®
then the BIOS settings are exposed through the Microsoft Windows
Management Instrumentation (WMI) by OMCI.
ASF Alerting
In previous versions of OMCI, environmental alerts were sent as Desktop
Management Interface (DMI) alerts. With the introduction of ASF, the
environmental alerts are handled by the ASF NIC. ASF monitors the
environmental probes at a very low level and sends out a Platform Event Trap
(PET) when an event occurs. Where applicable, OMCI notifies the local user
of the alert. For information on which PET a specific model of Dell system
supports, see the system's Setup Guide.
ASF is a DMTF management standard that specifies "pre-operating system"
or "operating system-absent" alerting techniques. The standard is designed to
generate an alert on potential security and fault conditions when the
operating system is in a sleep state or the system is powered off. ASF is
designed to supersede previous operating system-absent alerting
technologies.
WMI Alerting
Local alerting involves displaying user messages and writing to the Windows
event log. Remote alerting is accomplished through WMI indications. When
OMCI detects an event, it generates an alert, which can be transmitted
through the WMI service to a remote management application that is
subscribed to that alert type.
When an alert is generated, OMCI supports three types of notification:
•
•
•
NT event log
Remote
Console
In OMCI, each type of event (for example, CurrentProbe, TemperatureProbe,
Smart, and so on) that gets logged is provided with an unique event ID
number. The events have unique IDs to allow log scraping; this way you can
programmatically look at the event log and determine what OMCI events have
occurred.
32
Alerts
You are also provided with an option to receive either a single alert or a limited
number of alerts of the occurrence of an event, of a given type. You can mask
out specific events and can generate single alert messages for only those events.
The Dell_IndicationStaticValues class has the MaxNTEventLogNotifications
MaxDisplayNotifications, and the OccurrencesCount properties, which
control the number of notices of each alert condition that are sent to the NT
,
event log and to the local display. For example, setting a value of 0 will not send
any notices.
You can change any attribute or CIM class through standard CIM editors.
The following properties in the Dell_IndicationStaticValues class control the
number of notifications of each alert condition that are sent to the NT event
log and to the display. You can modify the below listed values through
standard CIM editors or through scripts.
•
•
•
MaxNTEventLogNotifications: The maximum number of event
notifications sent to the NT event log. Values are 0=never send, 1=first
occurrence only, 2=first and second occurrences, and so on. The special
value of
–1 sends all occurrences. The default value is –1.
MaxDisplayNotifications: The maximum number of event notifications
sent to the local display. Values are 0=never send, 1=first occurrence only,
2=first and second occurrences, and so on. The special value of 1 sends
all occurrences. The default value is 1.
–
–
OccurrencesCount: The number of event notifications of the given alert
that have occurred since the last reset. The initial value is 0. Setting
OccurrencesCount to 0 restarts the sending of notices.
Since the instances of the Dell_ IndicationStaticValues class are stored in
the WMI repository, the above data is persistent across shutdown, restart,
sleep, hibernate, and standby modes. You can reset the OccurrencesCount at
reboot by installing a script to run at startup.
NOTE: You are not allowed to make changes to some properties including the
MaxDisplayNotifications and MaxNTEventLogNotifications in the
Dell_IndicationStaticValues class in the CIM repository unless the User Account
Control (UAC) in Windows Vista is turned off, or the user is the Administrator
account.
Alerts
33
The following properties in the Dell_Configuration class allows you to
control the notices sent to the NT event log and to the local display based on
the severity of the event:
•
GlobalNTEventLogSeverityLevel: Controls the notice to the NT event
log based on the severity level of the event
•
GlobalDisplaySeverityLevel: Controls the notice to the local display based on
the severity level of the event
OMCI recognizes the following eight WMI severity levels (represented by
integers 0 through 7):
•
•
•
•
•
•
•
•
UNKNOWN = 0
OTHER = 1
INFORMATION = 2
WARNING_DEGRADED = 3
MINOR = 4
MAJOR = 5
CRITICAL = 6
FATAL_NONRECOVERABLE = 7
NOTE: Events with CRITICAL severity will cause OMCI to shut down the local
system after a 60-second delay. The GlobalDisplaySeverityLevel property in the
Dell_Configuration class should always be set to 6 or below; otherwise, the system
will not receive a shutdown command from OMCI.
34
Alerts
The lowest WMI severity level that OMCI sends is
WARNING_DEGRADED and the highest is CRITICAL. The severities of
OMCI 7.x events are listed in Table 4-1. OMCI sends local alerting and
remote alerting for all the listed events.

Troubleshooting
Wakeup on LAN
If Wakeup on LAN does not function on a client computer system, perform
the following checks:
•
•
•
Use either Dell™ OpenManage™ IT Assistant or system setup on the
client system to verify that Wakeup on LAN is enabled. See your Dell
system documentation for detailed information.
Ensure that the correct Network Interface Card (NIC) driver is installed.
Updated drivers are available on the Dell support website at
support.dell.com
.
Perform the following steps:
1
In Device Manager, double-click the NIC to open the NIC properties
window.
2
3
Click Configure
.
On the Advanced tab, set the Wake-up property to Magic Packet.
Remote Connection to WMI and Remote
BIOS Update
If Common Information Model (CIM) information for a remote client
computer system is not available to the management application, or if remote
BIOS update, which uses Distributed Component Object Model (DCOM),
fails, Access Deniedand/or Win32:RPC server is unavailable
error messages may be displayed. If you encounter these error messages,
perform the following troubleshooting steps:
•
To verify that the client system is connected to the network, at the
command prompt on the server, type:
ping <Host Name or IP Address>and press <Enter>.
Troubleshooting
45
•
If both the server and the client system are in a domain, perform the
following steps:
–
Verify that the domain administrator account has administrator
privileges for both systems.
–
If you are using IT Assistant on the server system, run the IT Assistant
ConfigServices utility (configservices.exe found in the /bin directory of
the IT Assistant installation directory). Configure IT Assistant to run
under the account of the domain administrator, and verify that DCOM
and CIM are enabled. See the IT Assistant User’s Guide for information.
–
If you are using IT Assistant, use the domain administrator account to
configure the IT Assistant subnet discovery for the client system. If
the system has already been discovered, remove the system from the
list of discovered systems, configure subnet discovery for it, and then
rediscover it. See the IT Assistant User’s Guide for information.
•
If both the server and the client system are in a workgroup (not in a
domain), perform the following steps:
®
®
–
If the client system is running the Microsoft Windows XP
Professional or Windows XP Professional x64 Edition operating
system and the server is running Windows 2000, verify that Service
Pack 2 or later is installed on the server.
–
If the client system is running a version of Windows XP and is not part
of a domain, edit the registry to allow remote connection with
administrative privileges.
NOTICE: Back up your system data files before making changes to the
registry. Incorrectly editing the registry may render your operating system
unusable.
To make the registry change on the client system, click Start→Run,
then type regedit, and click OK. In the Registry Editor window,
navigate to:
My Computer\HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Control\Lsa
Set the forceguest value to
0
(by default it is 1). Unless you modify
this value, the user remotely connecting to the system has guest
privileges only, even if the supplied credentials should provide
administrative privileges.
46
Troubleshooting
–
–
Create an account on the client system with the same user name and
password as an administrator account on the system running your
WMI management application.
If you are using IT Assistant, run the IT Assistant ConfigServices
utility (configservices.exe found in the /bin directory under the IT
Assistant installation directory). Configure IT Assistant to run under a
local administrator account, which is also now an administrator on the
remote client. Also, verify that DCOM and CIM are enabled. See the
IT Assistant User’s Guide for information.
–
If you are using IT Assistant, use the administrator account to
configure subnet discovery for the client system. Enter the user name
as <client machine name>\<account name>. If the system
has already been discovered, remove the system from the list of
discovered systems, configure subnet discovery for it, and then
rediscover it. See the IT Assistant User’s Guide for information.
•
Perform the following steps in order to modify user privilege levels for
connecting remotely to a system’s WMI:
–
–
–
–
Click Start, click Run, type compmgmt.msc, and then click OK
Navigate to WMI Control under Services and Applications
Right click WMI Control and then click Properties
.
.
.
Click the Security tab and then select DellOMCI under the Root
tree.
–
–
Click the Security button.
Select the specific group or user that you want to control access and
use the Allow or Deny checkbox to configure permissions.
•
Perform the following steps to connect to a system’s WMI (root\dellomci
from a remote system using WMI CIM Studio:
)
–
Install WMI tools along with CIM Studio on the local system and
install Dell OMCI on the remote system.
–
Configure the system’s firewall accordingly for WMI Remote
Connectivity. For example, open the TCP ports 135 and 445 in
Windows Firewall.
Troubleshooting
47
–
Set the Local Security setting to Classic - local users
authenticate as themselvesfor Network access:
Sharing and security model for local accountsin
the Local Security Policy.
®
–
–
In case of Windows Vista , disable UAC on the system.
Now connect to the system’s WMI (root\dellomci) from a remote
system using WMI CIM Studio (for example,
\\10.94.174.167\root\dellomci
)
–
Enter the Administrator credentials of the target remote system if
prompted.
for more information.
Installation Problems
If you are unable to complete installation of OMCI, check the following:
•
•
•
You must have administrative rights on the target system.
The target system must be a Dell system with SMBIOS version 2.3 or later.
The system must be running the Microsoft Windows operating systems
listed in the "Supported Operating Systems" section.

Glossary
The following list defines or identifies technical terms, abbreviations, and
acronyms used in this guide.
ASF
Abbreviation for Alert Standard Format—Defines remote control and alerting
interfaces for operating system absent environments.
BIOS
Acronym for basic input/output system. BIOS refers to the software code run by
a system when first powered on. The primary function of BIOS is to prepare the
systemsothatothersoftwareprogramsstoredonvariousmedia(suchasharddrives,
floppies, and CDs) can load, execute, and assume control of the system.
This process is known as booting up.
BIOS can also be said to be a coded program embedded on a chip that recognises
and controls various devices that make up the system.
CIM
Acronym for Common Information Model – the CIM Schema is a conceptual
schema that defines how the managed elements in an IT environment (for
instance Computers or Storage Area Networks) are represented as a common set
of objects and relationships between them. CIM is extensible in order to allow
productspecificextensionstothecommondefinitionofthesemanagedelements.
CIM uses a model based upon UML to define the CIM Schema.
CIMOM
Acronym for CIM Object Manager. The WMI management infrastructure
includes the CIM Object Manager, which is the interface and manipulation point
for CIM objects and information. It acts as a facilitator in gathering information
and manipulating object properties. The CIMOM stores data in an area called
the WMI repository.
Glossary
75
CLI
Abbreviation for command line interface. A CLI displays a prompt, the user types
a command on the keyboard and terminates the command (usually with the
Enter key), and the system executes the command, providing textual output.
CMOS
CMOS which stands for complementary metal-oxide semiconductor, is a major
class of integrated circuits. CMOS chipsincludemicroprocessor, microcontroller,
static RAM, and other digital logic circuits. The central characteristic of the
technology is that it only uses significant power when its transistors are switching
between on and off states. Consequently, CMOS devices use little power and do
notproduceasmuchheatasotherformsoflogic. CMOS also allows a high density
of logic functions on a chip.
COM
®
Acronym for Component Object Model which is a Microsoft platform for
software componentry. It is used to enable interprocess communication and
dynamic object creation in any programming language that supports the
technology. The term COM is often used in the software development world as
anumbrellatermthatencompassestheOLE,OLEAutomation,ActiveX,COM+
and DCOM technologies. Although it has been implemented on several
®
platforms, it is primarily used with Microsoft Windows .
DCOM
Acronym for Distributed Component Object Model which is a Microsoft
proprietary technology for software components distributed across several
networkedsystemstocommunicatewitheachother. ItextendsMicrosoft'sCOM,
and provides the communication substrate under Microsoft's COM+ application
server infrastructure.
device driver
A program that allows the operating system or some other program to interface
correctly with a peripheral device, such as a printer. Some device drivers—such
as network drivers—must be loaded from the config.sys file (with a device=
statement) or as memory-resident programs (usually from the autoexec.bat file).
Others—such as video drivers—must load when you start the program for which
they were designed.
76
Glossary
DLL
Abbreviation for Dynamic Link Library which is Microsoft's implementation of
the shared library concept in the Microsoft Windows operating systems. These
libraries usually have the file extension DLL, OCX (for libraries containing
ActiveX controls), or DRV (for legacy system drivers). The file formats for DLLs
are the same as for Windows EXE files—Portable Executable (PE) for 32
Windows, and New Executable (NE) for 16 bit Windows. As with EXEs, DLLs
can contain code, data, and resources, in any combination.
-bit
-
In the broader sense of the term, any data file with the same file format can be
called a resource DLL. Examples of such DLLs include icon libraries, sometimes
having the extension ICL, and font files, having the extensions FON and FOT.
DMI
The Desktop Management Interface (DMI) generates a standard framework for
managing and tracking components in a desktop, notebook or server computer.
Essentially, totheuser, itisatableprovidedbythepersonalcomputerBIOSwhich
can be parsed and which gives information about the BIOS and the system in a
standardized way. Previously, such complete information was not available from
a standardized source in the PC.
Due to the rapid advancement of DMTF technologies, such as Common
Information Model (CIM), the DMTF defined an "End of Life" process for its
Desktop Management Interface (DMI), which ended 03/31/2005.
DMTF
Abbreviation for Distributed Management Task Force (formerly
Management Task Force ). DMTF is a standards organisation that develops and
maintains standards for systems management of IT environments in enterprises
and the Internet. These standards allow building systems management
infrastructure components in a platform independent and technology neutral

way. They provide for systems management interoperability between IT products
of different producers, without costly transformations and adaptations.
DOS
Acronym for Disk Operating System.
ECC
Abbreviation for Error-Correcting Code. It is a code in which each data signal
conforms to specific rules of construction so that departures from this
construction in the received signal can be automatically detected and corrected.
Glossary
77
firmware
Software (programs or data) that has been written onto read-only memory
(ROM). Firmware can boot and operate a device. Each controller contains
firmware that helps provide the controller's functionality.
MAC Address
Acronym for Media Access Control address which is an unique identifier attached
to most forms of networking equipment. Most layer 2 network protocols use one
of the following three numbering spaces managed by the IEEE: MAC
and EUI 64 which are designed to be globally unique.
-48, EUI-48,

Magic Packet
In early implementations of Remote Wake
a power off state by sending a Magic Packet. A Magic Packet is an Ethernet packet
that contains an adapter s MAC address repeated 16 times in the data field. When
an adapter receives a Magic Packet containing its own MAC address, it activates
the server s power. This enables network administrators to perform off hours

maintenance at remote locations.
MOF
There are potentially many ways in which CIM management information could
be represented to exchange information. The CIM Specification defines a
language based on the Interface Definition Language (IDL) called Managed
Object Format (MOF).
MOF is the standard language used to define elements of CIM. The MOF language
specifies syntax for defining CIM classes and instances. Compilation of MOF files
provides developers and administrators with a simple and fast technique for
modifying the CIM Repository.
OMCC
AbbreviationforDell™ OpenManage™ ClientConnector. OMCCisaone-to-one
management console for local and remote system administration. It is a client
management application that allows the user to view and configure OMCI
properties and perform remote management functions such as shutdown and
BIOS updates.
RAID
Acronym for redundant array of independent disks. In computing, RAID is a system
which uses multiple hard drives to share or replicate data among the drives.
Depending on the version chosen, the benefit of RAID is one or more of increased
data integrity, fault-tolerance and throughput or capacity compared to single drives.
78
Glossary
SMART
Acronym for Self
-Monitoring, Analysis, and Reporting Technology, which is a
monitoring system for system hard disks to detect and report on various indicators
of reliability, in the hope of anticipating failures. SMART warns an user or the
system administrator of an impending drive failure while time remains to take
preventive action, such as copying the data to a replacement device.
SMBIOS
Acronym for System Management BIOS which is a specification to lay out data
structures (and access methods) in a BIOS, which allows an user or an application
to store and retrieve information specifically about the PC in question.
WBEM
Abbreviation for Web Based Enterprise Management. Defines protocols for the
interaction between systems management infrastructure components
implementing CIM, a concept of DMTF management profiles that allows
definingthebehavioroftheelementsdefinedintheCIMSchema,theCIMQuery
Language (CQL) and other specifications needed for the interoperability of CIM
infrastructure.
WDM
Abbreviation for the Windows Driver Model in computing. Also known as the
Win32 Driver Model, the Windows Driver Model defined a unified driver model
for the Windows 98 and Windows 2000 line by standardizing requirements and
reducing the amount of code that needed to be written. WDM drivers will not
run on operating systems earlier than Windows 98 or Windows 2000 and is
designed to be forward-compatible but not backward-compatible.
For example, a WDM driver written for Windows 2000 will load and function
under Windows XP, but cannot take advantage of any new WDM features that
were introduced in Windows XP. A WDM driver written for Windows XP will
not load under Windows 2000.
WfM
®
Abbreviation for the Intel Wired for Management standard. WfM technology
was used in client
network interface cards) and management software applications. It defines a
baseline set of requirements for managing hardware, including requirements for
instrumentation, remote wake up, power management, and service boot
capability. It enables centralized system management, including inventory,
fix/repair, configuration, and diagnostics, and provides for off hours maintenance
to minimize downtime. WfM includes support for DMI and allows a technician

to diagnose and upgrade a remote system while the user of that system continues
working on other tasks. It also allows software upgrades in the background or
during scheduled hours.
WMI
Abbreviation for Windows Management Instrumentation which is a set of
extensions to the Windows Driver Model that provides an operating system
interface through which instrumented components can provide information and
notification. WMI is Microsoft's implementation of the Web-Based Enterprise
Management (WBEM) Standard from the Distributed Management Task Force
(DMTF).
WMI allows scripting languages like VBScript to manage Microsoft Windows
personal computers and servers, both locally and remotely.
