This sounds silimar to a problem we've experienced before with multiple nics on a machine...Its a hard one to explain but it has to do with having the route table mess things up when trying to talk to the local subnet. Take a look at the route table and follow the rules for a given packet and see if the packet is being routed through the wrong interface and thus off to the wrong subnet. This one had our NT guys confused for a while But the again...NT...confused...whats the difference. hehe. Let me know if this helps...
