The backuppc server and the slow machine are both plugged into the same Dell switch.
I have also observed that the other three PC's that were bought at the same time are not on the same switch. They actually pass through a 100 Mbps router and two switches. The more direction connection is actually a slower one.

Unless this is a common problem that someone has a canned answer for, which is doesn't look to be, I think you're stuck with process of elimination. Some ideas: - Check for any BackupPC client configuration differences, if it's in separate files (or could be made that way) then using a tool like 'diff' would highlight configuration differences. - Check network throughput on the client for other file transfers. Is the BackupPC server the only one that gets poor throughput to it? What about manually copying a file over cifs. - Is the client on the same subnet or physical switch as the other 3 identical machines that work correctly? If not, can you temporarily make it that way for testing?
