The users do have one thing in common, that would be the global group that they are all a memeber of that is inside the local admin group. Other than that, it has happened on NT4, 2K and XP - regardless of geography. One user could be in Nebraska and another in California.

It doesn't happen a lot, but enough to be a concern if I need to roll out a patch or something like that. What is strange is that the same users can log on to another PC and the function returns that they have admin rights.

This would make you think the problem is with the other PC. But, I can log on to the other PC with a test account and everything checks out as it should. [Confused]
