Be sure to test the obvious thing - this sounds like what would happen 
if you had a duplex mismatch between the server and switch.  If the 
switch is managed and configured to force full duplex, you have to have 
the matching setting in the OS configuration.  You are probably better 
off letting both negotiate.  If either ifconfig or the switch port stats 
show any errors, look for the problem in the network first.
