Needed to kill a connection so I get could logged on recently to a server and didn't have the server tools loaded, ran across this useful link on How to Kill Terminal Services Connection. Might come in handy for you some day. It's hosted on HacksZine.com, similar to the MakeZine.com site (the latter being very interesting, if only to find time to try all the ideas they come up with!)
