Could be related to XP's QOS layer - check the nic properties and remove
that component.
IIRC XP reserves 20% of bandwidth for apps that require QOS.

If your on the Universities LAN, then only god can help you I'm affraid.
Things to look for, half/full duplex on your ethernet card.
give us the output from i/f config. before and after the copy. on XP
dunno, I'd say wipe it, ;-), and install windows 2000, but I can't say
that, because XP is microsoft's brand new flag ship operating system,
and I B E L I V E them....;-)
try other clients see if it's a layer 7 problem.
(win 95, win 98, etc etc) see if microsoft have disabled linux
interoperablity again. ;-).
I think you really need to provide more information about your machine.
version numbers, kernel, samba version, an output from your dmesg might
be nice, but you'll have to buy me beer to look at it ;-)...virtual beer
perhaps.
I had a similar problem, and found out it was a high number of error's
being generated by a dodgey 10/mb shared hub.... oh dear...
netstat -s also quite nice, if you know how to read da stats.
so, here's some things to try before you break out the network
sniffer...
sniff..sniff.
Laters.
