Strange file access on Xp SP2 client

I have an application that is launching from a mapped drive. Normally things
will launch and run fine. However lately we have been having issues with the
application appearing to be hung. Sometimes if we wait (15-90 seconds)
things will return and life appears to be okay.

Well trying to troubleshoot this issue, I loaded Sysinternals Filemon to see
what was going on. I saw that some of the files were being accessed via the
mapped drive and some were via unc path. I am not sure how that can happen.
Every time I have tried to start the application with netmon and filemon
running, all files will be accessed using the mapped drive. I cannot get it
to fault when trying to capture it (of course). However, if I come back
about an hour later, sometimes it will be fine (still using mapped drive
access) and other times a couple of files that are opened will be using unc
and the rest of the files will be opened via mapped drive.

I am at a loss to try and figure this out. It appears that when something on
the network hiccups, it changes, but I am having a hard time capturing that
to prove it. We applied sp2 to all or workstations (all xp) because of the
issues with mapped drives disconnecting with open files, and it appears to
help, but not solve the problem.

I am open to suggestions as to what to look for or check. I have been
trying for weeks to capture it.

Thanks

If you can get the App to run with UNC paths, then forget the mapped drive.

16 bit code doesn't like it. Need the mapped drive.

The "bit level" doesn't matter,...it is how the thing accesses
"locations",...even 16bit applications can use UNC pathes. Anyway, mapped
drives "are what they are",..which is trouble,...so my only solution is to
find a way to not use them any more. We had a situation like that here but
we the eventually able to get away from it.
