Back in the day when I used to support a lot of Netware networks, problems like 
this were often caused by 10/100 duplex mismatches caused by crappy 
autonegociation between the switch and the server's network card.  Usually we 
made the problem go away by forcing the server NIC (and the switch port, if we 
had a manageable switch) to 100 mB Half Duplex.

Also, are you running Samba on Ubuntu, with Active Directory?
