Performance difference between two "identical" win2000 clients

Hi!
We have two Win2000 Pro clients accessing the same samba server. As far
as we can tell, tcp/ip is configured exactly the same for both PCs. Also,
as far as we can tell, the samba server is not set up to do anything
different based
on the client.
The first PC, PC1, is very slow and a sniffer shows many more SMB
messages than
the second PC, PC2, that is very fast. By slow I mean UI response times
of 15 to 30 seconds,
while the fast PC response times are more like 2 to 5 seconds. The UI
I'm using is
Visual SourceSafe.
I've listed below the messages that the sniffer caught for the two PCs.
Can anyone tell
me why the two PCs are communicating differently to the samba server?
Thanks!
Kevin
