I have their MSN.
Can I do it using their IP?
Also how can I find out their IP?

hey buddy :-) why you want to disconnect yaar, just for fun

check the netstat at the time when he connects to you

go to the system directly and find out the ip address. or if u re connected with LAN to that system, try using the command 'shutdown' from cmd.
