DB/2 Problems after swapping in new network card!!

[Guest_imported]

We are running 2 db/2 servers here, and they have been running just fine for the longest time. But recently we upgraded our network to full-duplex speed, and so I popped in a couple new network cards in our db/2 servers. After doing so, none of our client workstations can connect to either database (getting a netbios error). I can access the network on both of the servers, just not connect to either database remotely. I did notice that when the databases start I am getting a message saying that "one or more services failed to start" - which sounds like theres a problem with the netbios protocol. I've tried all I know to do though (other than reinstalling the whole database and all - uggghhh)....any suggestions?

Thanks
