Is this your firewall or server box, or just a workstation in the lan?
If you have a different nic, try swaping it out.
Are packets slow? or are you dropping packets? Run some ping tests.
Try running a tcpdump to see what kind of packets are hitting your nic.
I've seen Appletalk, IPX and tcp/ip traffic on a segment slow down because of
conflicting addressess.
