We have a laptop in our office that keeps losing domian users in the local administrator group but not domain user groups. This happens everytime the user restarts the machine and we then have to manually add him in again. He is using Windows XP.
This has occured since we moved his domian last week, though we did if for 30 other users as well and nobody is experiencing the same issue.
Has anybody come across something similar or can anybody provide me a possible resolution?
