Sometimes I need to read performance counters from a machine in a different domain when I run load tests. This can be done in a few easy steps on the target machine:
- Enable the guest account
- Add the guest account to the Users and Performance Monitor Users group
This will also remove the “Unable to connect to machine” error message if you use perfmon.
Remember to disable the guest account when you are done.
This recipe is only valid for Windows 2003 Server. If you need to read the counters from a Windows NT or Windows 2000 server take a look at this article:
