One way is to install sshd on the Windows box, then you can ssh in and run any command line tools you like.

It can be a pig to get sshd installed on Windows, I think I used this http://sshwindows.sourceforge.net/ installer in the end on my Windows server.

Edit: How annoying. Just checked out the "net" command via ssh on my Windows box. While running "net" commands do work, you don't get to see the output of the command. It must be doing something non-standard to output its text.

Typical...
