What message? A broadcast message over your network, or an e-mail message?

Why would you think that a LAN would prohibit spoofing?

they use the 'net send' of windows. Does these messages also contain the ip of the computer they were sent from?

Not that I am aware of. They do contain the machine's name, however. Can you not just cross-reference that back to the IP address?

these guys use a program to change that name displayed in the message KOM UIT DAAAAA!!!

Oh, I just assumed that NET SEND was being used. The only recourse that I know of is to disable the Messenger service on your machine.
