A little intro: I'm not a server admin, but I do some tech support for a small software company whose product requires users to have full control permissions to a mapped drive on the server in order to share files required for multi-user use. I believe our software uses an Access database.
My question is, let's say you have three user groups, A, B, and C. In order for our software to function correctly, a user will need full control privileges (not just read/write) to the Z: drive. Let's say user group A and B has this full control to the Z: drive, but user group C does not have any privileges to Z:. If a user is a member of all three user groups, would there ever be a case where they didn't have full control to the Z: drive?
I believe I have seen this with one company, they were having issues with our software and we had them give all their user groups full control and the issues went away, but I'd like a little more information on how user groups and permissions are set up, and if this could be causing problems with our software. FWIW, I have no way to change what's programmed in our software, so suggesting it should work differently (which it probably should) is futile.
