Just a dumb idea: are you sure the two boxes have different mac
addresses?
Slightly less dumb idea: grep through /etc looking for your IP
address and MAC address. Maybe the system is consulting some dumb
file and getting the wrong address that way.
Much less dumb idea: start up tcpdump on both machines and see
what actual traffic is causing the error.
