I think you'd need to write your own shell-like daemon for Windows. I've considered doing that for my home network just so I could use some of the family's machines when they're away, etc. But since Windows doesn't come with a real shell built in, rolling your own would be your only real recourse.

When I was in high school, people used a tool for Windows called Fictional Daemon to get a remote telnet server that could access a command prompt, start, stop, and list running tasks, etc.
