When trying to use Performance counters with WCAT testing I was getting this error on the final report:

An error occured collecting server information data. Check that WMI is available.

Looking back at the command prompt on the controller I also saw this:

ERROR:Unknown error -1073738789 (c0000bdb)

Wireshark and Procmon did not really indicate any problems. In my situation I was logged into the WCAT controller as a domain user which did not have administrative access on the web server I was trying to start the Perfmon counters on.

After adding this domain user to the administrative users group on the web server, the WCAT test successfully collected the Performance counters specified in my settings.ubr file.
