阅读更多关于 Starting a process remotely in Powershell, getting %ERRORLEVEL% in Windows

I'm doing this from an automated test framework from a Win2003 machine, the test framework executes commands without launching a console, some of the system under test is running Win2008. I've written scripts to choose the performance counters based on roles assigned to the servers. My problem(s): logman can't start or stop counters on machines that run a later version of the OS. psexec can be used to run logman remotely, but psexec likes to hang
