Ditto.  We had several systems that allowed network file server access,
but when you printed a file from Microsoft Word, then exited Word, the
PC locked up.  It turned out the problem was we had used the DOS APPEND
command to add directories to our PATH.  I suspect that PC-NFS MAY pick
up a pointer to the PATH when it starts, and that APPEND is changing the
location of the PATH.  In any case, PC-NFS is not at all good about
figuring this out.

I'm currently trying to get the InSet text/graphics integrator working
with Microsoft Word and PC-NFS.  InSet grabs the printer interrupt (17H),
but so does PC-NFS.  No problem, I say, I'll install InSet first, then
PC-NFS.  That way they will chain together.  (At least Inset Systems
says it works with other networks).  Nope.  Doesn't work with PC-NFS,
though I still have determined who the most guilty party is.

Our experience has been that Sun answers mail and calls back, and really
tries to help us solve the problems -- but the PC-NFS guys know nothing
about the Sun side of networking, and the Sun networking people are
almost completely ignorant of PC-DOS -- to say nothing of the PC-NFS
stuff.

My impression is that the PC-NFS guys are principally useful as 
facilitators -- they talk you through the process by which YOU figure
out what's broken -- they didn't figure out that APPEND was blowing us
out of the water -- we did.
