Hi everyone. Is there any experience with changing Administrator password in Activ Directory if the Administrator is also the Exchange 2000 service account? I have done this before, and my E2K server lost contact to the AD about 24h later. Afterwards no one was able to authenicate themselfs to get into the mailboxes, and I lost quite a lot of mails ins contact information not to mention Time and credibility. (but I'm mentioning it anyway...) I've changed the password again now, but this time I have a fairly good backup strategie running, But I can't afford a testlab to fully test our setup. I can't see why I shouldn't be able to simply change the password, but then it wouldn't be the first time Microsofts Logic completly baffels me... Thanks for any help Christian
