RMA 301 - unable to locate the processor performance object

Hm. Looks like some performance counters information is corrupted in the registry or perfOS.dll is corrupted as well.
Are you able to add "Processor" performance object to standard Windows "Performance" applet? Is it working?

Could you try to copy perfOS.dll from another Windows 2003 server? It might help.

Anyway, I would suggest you to rebuild Performance Counters library according to the following article: http://support.microsoft.com/?kbid=300956

BTW. Could you also check your hard drive for errors? Problems with hard drive may lead to such a problem.

Regards,
Max

Thank you very much for your aid. I followed the steps as per the KB article, and copied a fresh PerfOS.DLL from the I386 directory, then restarted the server.

The issue has been resolved.

Great

Also I would recommend to check file system for errors. May be DLL was corrupted due to file system error...
