Runtime Error 68 when accessing Network Share

I have a program that accesses an access database on a network share. The program had worked properly up until my PC upgrade from XP to Win 7. After some effort, I was able to get VB loaded and configured so the IDE would properly load the program. I receive Runtime error 68 when I attempt to update a directory control for my Drive "S:" which is on a network share. The share is active and I can access the files. I recall having this issue before and believe it is a set up or configuration issue with VB on the upgraded O/S.

There have been no changes to the application code, which has worked well for the past year or so prior to the Win 7 upgrade.

Any thoughts.
