I did ping the PDC server from the workstation when running Linux and even got 
a lease from it. All the lights on the new switch indicate everything is good, 
and the PDC server can access the Internet. Reboot the workstation into XP, 
and the workstation can't find the PDC (domain not available).* Since I can 
have two way traffic with the new switch in place, unless someone can point 
out a flaw in my logic, it can't be the switch.

The switch is also a standard 5 port home switch (not my choice of equipment 
BTW), and does not include a firewall. And if I remove the switch, and go back 
to the original connection, with NO other changes (workstation and server), it 
works. I also considered it could be a bad cable, since I do use a new cable 
with the switch to connect the server to the new switch. But if it was a bad 
cable, how can I get a lease through it (and ping)?

I should add that the original 3 switches are all different models, but none 
have any firewall capability.

* Since I can't log in, I can't easily test the XP side of things to see if I 
get a lease, and I'm not in charge of the workstations, so getting the local 
admin password is not a simple matter. Politics...
Fail to learn history-repeat it.
Fail to learn rights-lose them.
Learn both-get screwed by previous two groups.
