For what it is worth, I just backed up a notebook that has an 80 GB drive to a 
Samba drive using Norton Ghost. The resulting data created a bunch of 2 GB 
files, all of which read back onto a new drive without any problem.

This might suggest that the problem you are seeing is not a Samba problem, but 
rather one of either configuration or network hardware glitches.

FYI: Slow logons are suggestive of a netbios name resolution problem or else a 
bad NIC or HUB/switch.
