It was apparently another admin who thought about locking down the Domain Admins group in the Default Domain policy Restricted Groups setting. He put the group in there but then failed to put any users in the group. Thus we'd add back the appropriate users, and as soon as the policy refreshed, out they came again. I'll have to track this person down via the logs.

Jr [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 03, 2008 10:49 AM To: Active Directory Admin Issues Subject: RE: Members Disappearing from Group There is also something called AdminDSHolder or is it AdminSDHolder. Basically, it sees a lesser (than DA) with delegated access to the user object that is a DA and does not like that. I can't remember if it takes away DA or does something else. It was over a year ago when I ran into it. ________________________________ From: Campbell, Rob [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 03, 2008 11:43 AM To: Active Directory Admin Issues Subject: RE: Members Disappearing from Group Group policy can do this. ________________________________ From: Phil Hershey [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 03, 2008 10:39 AM To: Active Directory Admin Issues Subject: Members Disappearing from Group We recently staring experiencing an issue with members disappearing from groups to which they normally belong. Today it was 4 users suddenly no longer being members of the Domain Admins group. Any ideas what might be going on? I'm reasonably sure I don't have a rogue administrator screwing with me. I'm concerned about general AD corruption or even a root kit. Thanks.
