Donald,
The easiest method to track down a system that is masquerading it's source information (MAC/IP/etc) is to have managed infrastructure. Peel your infrastructure like an onion, searching for the source port of the traffic.
On the other hand, if you don't have managed switches; you may be forced into segregating your network in to smaller and smaller components. Analize both segments to determine which side the traffic is still visible (using a sniffer), and then separate it again, and so on, until you find the switch that has the traffic. Then it's just finding which host on that switch is the culprit.
Cheers!
Eric
