alternatively (if the above doesnt work, but it should), you can use the
dos fullname function (interrupts escape me now, but i will get them if
someone wants them) which will return "\\server\volume\path..." if it is
a network and "drive:\path..." if local.

i am posting this because many people (even netware-versed ones) are 
unaware of the \\server\volume convention in dos.  it works even in
programming, which is GREAT if you are not sure if your user has a 
certain drive mapped to wherever and dont want to go to the trouble of
mapping it (or a temp one) yourself.  also, you can do dos commands like
cd \\server\volume (heck, do it from your C: drive, ha ha).   some cmds
(like dir) dont accept this format.
