If you are using DHCP, use arp, find the offending machines MAC address, then configure the DHCP server not to give that MAC address an IP address, or one that won't route or similar.

Then wait for the scream :-)

You might also look-up the MAC to see who made the NIC, to help identify which machine it is.
