Hmmm, it sounds like there is something wrong with how the network is
set up on the "server" and that the Clipper app is just the victim of
something going on deeper down in XP. Look at drivers and protocols
for example. Is there anything you don't need that can be turned off?
Any extra protocols besides TCP/IP? And check if the performance is
identical if you let one of the workstations take the role of server
(with mapping vs substing locally and mapping over the network).

What happens if you copy a large collection of files to the C: drive
from a mapped drive and from a substed drive respectively using the
command line or Explorer? Any difference there?

IIRC there was a change introduced in XP SP2 that affected write
performance, but I can't remember the exact details and I haven't
personally seen that problem. Perhaps someone else can jump in.

You might also want to take a look at Nick Ramsay's networking page at
http://www.witzendcs.co.uk/html/nt_networking.html

The registry settings affected by Nick's reg files are not primarily
speed related, but they are considered "required" for systems where
Clipper applications and similar file sharing apps are run. So it is
generally a good idea to apply them. They _do_ solve som other common
problems.

Klas
