Active directory changes back over night

I have this problems, that i change the user’s password, but the next day it have change back to the old password.

I remember that i have this problems early on some other systems, but can’t seem to find the Microsoft kB about this.

On this system there are only one DomainController, so it not something synchronisation that have gone wrong over night.

Could someone help me out here?
