It seems to be when you are a member of Domain Users, IS, and ISSupport, but I haven't verified there are problems with being in other groups yet. I wanted to resolve this issue first. So the drive mappings should be F:, I:, P:, and Z:. I also removed the Y: /delete line and it still has problems. I put that in to test removing some mapped drives, so it is now removed from the script.
