I've been using PerfMon to monitor some SQL Server Stats for a while but we recently moved our production SQL Server to a different domain and I'm having trouble setting this back up. When I try to add the counters in it recognises it but then when I expand a section I get Can't Load Counters.

We have a trust between the domain and I've added my local login account to the 'Perf Monitor Users' & 'Perf Log Users' group on the destination domain.

enter image description here

Anyone had this before or got any ideas?

I recognize this question is old but I had to finesse an answer under slightly different circumstances. This won't address domain trust issues. Still, given the number of views, I thought this was worthy of sharing. It worked for me on a Windows 7 machine.


  1. Elevate a cmd.exe's privileges (Run as Administrator) so you can runas another user.
  2. From the elevated command window, open a cmd window under the desired credentials, e.g. (runas /user:<doman>\<user> cmd).
  3. From the command window with the desired credentials run mmc (NOT PerfMon directly).
    • If you don't do this I don't see how to save the changes you make.
  4. In the MMC (Console) add the Performance Monitor snap-in (File | Add/Remove Snap-in...).
  5. Now you should be able to access the desired server(s) with the desired credentials. Also you can now save your work (File | Save As...).

In Windows 7

  1. Start, type cmd (search programs and files), right-click on the resulting cmd.exe and select Run as administrator. Accept the elevated privileges prompt (User Account Control dialog).
  2. In the resulting command window (Administrator: C:\Windows\System32\Cmd.exe), enter runas /user:<domain>\<user> cmd.
  3. In the resulting command window, "cmd (running as <domain>\\<user>)", type mmc
  4. In the resulting mmc window, "Console1 - [Console Root]", chose File | Add Remove Snap-in..., select Performance Monitor.
  5. Add your counters and now you can also save them.
