Well I started the restore and went home, so I don't know how many mounts it 
did, but the data was on 3 tapes

And it looks like it only mounted the tapes once, except for 006811, which got 
mounted 2 times:

During the restore, the "original" server did a backup, does  my restore 
somehow collide with the running backup?

FS039 is the fileserver, and my ws is WS25658

How many tape mounts did you see during  the restore?

I actually restored the files to my workstation, and the network settings are 
fine
Duplex mismatch does not cause the speed to go down to modem-speed from 1995....

your network sucks? (to put it mildly :) ) I'd check to see if there is any 
mismatch in duplex settings anywhere. Remember, auto-negotiation on the host, 
and a fixed 100 full-duplex setting on the switch will lead to a host at 
half-duplex and tons of collisions.
