I get the following error when trying to get some info from WMI on an Exchange 2003 server. Normally this works OK but on a bunch of servers it's failing. Anyone know whht's going on?

102 Invalid class when process matrix 0 WQL = Select ActiveUserCount, RPCRequests From Win32_PerfRawData_MSExchangeIS_MSExchangeIS

It's a local query. Unfortunately the query is being generated by a third party program and I can't easily access the query itself. I was kinda after some pointers to troubleshooting ideas ?

If this should fail, here's another suggestion from the Mothership:

I'm not strong with wbemtest but I think I can see the classes but not any instances. Does that make sense?

Yes.. I think I came across something similar a several years ago.. and I think I ended up "rebuilding" WMI


Dont know if you have tried this..

wmiadap /c
wmiadap /f

Restart WMI service

I've had a degree of success with some of the above as well as a few other bits and bobs I've found via Google. However, there's still a few servers that refuse to populate WMI with the counters despite my best efforts. I've tried doing a mofcomp.exe against the mdbperf.dll counter file in Exchange's bin folder, I've done lodctr /R, wmiadap /c and /f but to no difference in results.

WBEMTEST shows that there's no instances in WMI.

I'm stuck.

OK, so I've pretty much got this sussed.


lodctr /R "C:\program files\exchsrvr\bin\mdbperf.ini"
net stop msexchangemgmt
net stop winmgmt
net start msexchangemgmt
wmiadap /c
wmiadap /f

Does the trick. The counters were not being passed across into WMI because the Exchange services were starting AFTER the WMI service.
