couple of things right offhand. check and see what speed/duplex
settings the box is set for. they MUST match what the switch it's
plugged into is set for. in general, autonegotiate should be avoided.

second, it could STILL be name resolution. see if that box has itself
in /etc/hosts, and see what's in /etc/netsvc.conf....set it for local,
bind and that might help.
