Loss of WindowsXP Admin rights
I don't know if anyone could help me out with this.
Over the Summer I updated my XP images. I've just been to add a scanner to one of the reimaged Student machines, and it appears that the Local Administrator rights have been removed. I get the standard message when I try to access the Device Manager, Task Manager is greyed out, and the scanner driver install fails.
To make it more confusing, it only appears to be on specific (newer) models, not all systems.
The only time I've known something like this is through a virus or rootkit or something.
I have scanned everything, driverpacks etc, and wondering if it is either a Windows Update, Sysprep, or a device driver or something.
Does anyone know how to restore the Local Admin privileges as a quick workaround?
