Still having these two problems: Some users are not getting mapped drives when they log in. They don't seem to be running the script automatically. The errorlogging built into the script seems to be catching problems, so I know it works. These users aren't even generating logs, so I am assuming they aren't even getting to the executable for some reason. So that's problem One.

Problem 2 is that some users get their mapped drives ok, but a short time later the drive disappears from the network drives section of their My Computer. They can't access the drive at all, so I know it isn't just that the drive is not visible, it is actually not mapped anymore. Anyone have any idea of what might cause either of these two?

I have seen articles/posts elsewhere on the web similar to my problem One, though never any solutions. I have not seen anything like problem 2.
