Yes, have thought about that. ifconfig yields _no_ error of any type :(. I am
considering the possiblilty of a faulty NIC. We have had lots of fun with nic
related problems b4 (Not samba related), however, word documents, file copying
etc, is all very fast. Perhaps there is something special about the way Access
accesses its data ;)

That would be good - now, just have to work out how to drive 200 miles to play
with some network cables ;)
