Any idea.

When saving a file to a server via a VPN line. Intermittenly it can be
saved and some time it failed with error: writing error.In other testings,
copy a file to that destination folder could intermittenly come up with the
same symptom of problem.

Looking into the destination folder, temporary file was created instead.
e.g. saving an image named inform.jpg from Paint Shop Pro V.8, when it
failed a temporary file named SAV01.tmp was created.

This workstation runs nwc 491sp4

Server runs netware 6.5sp5

SLP DA is up and no slp error is logged.
