Invalid Class?

[UnOa]

We test several servers (40+), all with AHM 6.80, RMA 3.38.

We use WMI test to monitor free physical memory (select AvailableKBytes from Win32_PerfFormattedData_PerfOS_Memory)

On almost all servers this works great, however on 2 specific servers an error is returned: Invalid Class

What could be causing this?

Isuppose, on these specific servers installed Windows 2000, right? As I remember, Windows 2000 does not have Win32_PerfFormattedData_PerfOS_Memory class. You have to use Win32_PerfRawData_PerfOS_Memory instead.

Probably old Windows?
Windows 2000, Windows NT 4.0 and Windows Me/98/95 does not support this WMI class

Well, one of the servers is indeed a Windows 2000 Server, thanks!

However, the other one is in fact a Windows Server 2003 Standard Edition with Service Pack 1. It is in use as a Citrix Terminal Server.
Any ideas?

Actually, it is hard to say what is wrong with your server. Lets try to figure it out:
1. Please run wbemtest.exe utility to ensure the Win32_PerfFormattedData_PerfOS_Memory class is present on the system.

2. Type the following command at the command prompt on target server:

Code: Select all

wbemadap /f 

3. If foregoing command did not help, you may try to repair wmi setup. Please read carefully the following article, especially topic related to "Windows Server 2003, Service Pack 1": http://www.microsoft.com/technet/script ... mspx#EQKAC

4. Also you may try the following trick (you have to take responsibility ):
a) Stop the "Windows Management Instrumentation" service on the problem server.
b) On the problem server, rename the %systemroot%\system32\wbem\Repository folder to %systemroot%\system32\wbem\Repository\Repository.bak.
c) Copy the %systemroot%\system 32\wbem\Repository folder from a known good 2003 server to the problem server
d) Start the WMI service
