Supported Management and Alerting Agents
With Dell OpenManage software, agent is a general term applied to the software features of systems
management instrumentation. Degrees of support vary among agents. For example, IT Assistant
automatically discovers, displays, receives alerts from, and can perform actions on the systems managed
by Server Administrator, but IT Assistant can only receive alerts from certain storage device agents. See
the Dell OpenManage IT Assistant User’s Guide for a list of Agents supported by IT Assistant.
Upgrading IT Assistant After Migrating to Windows Server 2003
If a system with IT Assistant installed is migrated to Windows Server 2003, then upgraded to a more
recent version of IT Assistant, a problem may occur due to encryption differences between Windows
Server 2003 and earlier versions of Windows.
After an upgrade on a system that has been migrated to Windows Server 2003, systems configured with
the CIM protocol might no longer be discovered. If this issue occurs, reset the password for the CIM
user. In the IT Assistant user interface, go to Discovery and Monitoring, select Ranges and right-click
Include Ranges. Click New Include Range to run the New Discovery Wizard, where you can specify the
new CIM user name in the CIM Configuration window. See the IT Assistant online help for
additional information.
Other Known Issues for Microsoft Installations
• After the IT Assistant installation program installs MSDE and you reboot the system, the Windows
2000 Event Viewer logs an
ERROR
event with a
Source
value of
Server
, a
Category
value of
None
, an
Event
value of
2506
, and an error message stating:
The value named
MaxMpxCt
in the system's Registry key
LanmanServer\Parameters
was invalid. The
value was ignored, and processing continued.
MaxMpxCt
is a registry key of type
REG_DWORD
with values from 1 to 100. It provides a suggested
maximum to client systems for the number of simultaneous requests outstanding to this server. A
higher value can increase server performance but requires higher use of server work items. The default
value is 50. After MSDE 2000 or SQL Server 2000 is installed on a system running Windows 2000, the
registry key
MaxMpxCt
is created with the value
0x000001ff
(511), which is higher than its upper
limit. After you reboot the system, a Windows 2000 system has an
ERROR
event item in the System
Log of the Event Viewer. If you remove MSDE 2000 or SQL Server 2000 from the system, the registry
key will be removed, too.
• Directories might be left behind during an uninstall for reasons such as sharing violations or open user
interface connections. It is recommended that you close all open interface sessions before you perform
an uninstallation. Manually remove directories left behind in the default installation directory or the
user-specified installation directory. You might also have to manually remove the registry entries under
HKEY_LOCAL_MACHINE\SOFTWARE\Dell Computer Corporation\Dell OpenManage
IT Assistant
