Looking for a quick way to remotely uninstall the Configuration Manager agent from a system? Try this:

Psexec \\computer –u domain\user c:\windows\system32\ccmsetup\ccmsetup.exe /uninstall

A successful result looks like:

C:\windows\system32\ccmsetup\ccmsetup.exe exited on (computer) with error code 0.

The PsTools are available for download at http://technet.microsoft.com/en-us/sysinternals/bb896649.aspx. I have found these to be invaluable when remotely performing actions on systems.
