We just went through something similar at one client's site.

What we found was that the Cisco switches there don't auto negotiate 
effectively with the NICs on the Samba (and other) server(s) and 
workstations.

Once we forced all the NICs on the network to 100FD, our problems went 
away.  In other words, this wasn't a Samba problem at all.

On a Windows box, check the driver settings on the NIC to disable 
autoneg and force whatever your network infrastructure will comfortably 
support, usually 100FD.  

If you have heavy network traffic, you can set the workstations to 10FD 
and leave the servers at 100FD (or, leave the workstations at 100FD but 
add more NICs to the servers).

On the Samba box, you'll need to use ethtool or mii-tool, depending on 
your NIC, to make the changes. The man pages for these tools are pretty 
clear as to their usage.

Hope this helps,
Mark
