How do i see who is logged into remote desktop on my windows 2003

[Ross J]

server. How can i kick them off? I need the ability to kick off users from remote desktop from my 2003 server. I know how to log into the 3rd connection using command line-- but that does not do much good if that gets locked out as well. I saw a way to do it via command line, but i know there is also a way to do it within windows. Help appreciated.
