Sorry, i've been busy this week until now.

My OS is native german, but i hopefully doubt that MS ported such a quite important feature...

I'm 100% certain that i've set the rights in the right way

I have tried connecting to XP-boxes from other XP-boxes, i've tried it from other 2000-boxes, neither of them does work. In addition, i still have the problem that i can not run the WMIQuery-Script as a different user. TBH i can not run it even with any user. As soon as i enter User Information when calling WMIQuery it does not work, no matter what computer i try to access (Administrator account, user accounts, no matter what, it does not work, even when i try to access those that work without a user because the user on both workstations is the same)
