I’m having a problem with users accounts randomly (as far as I can tell) being removed from security groups. It has been happening over the last few months with different users and different groups, although one specific user has been removed from the same group 4 times now. These users have been in these groups for years without a problem then suddenly they are removed.
It is an AD 2003 environment with only 1 domain and 6 domain controllers. We only have 3 domain admins and none of us are changing the groups. None of our users are admins of any kind, not even local to their PC’s.
If anyone has experience or suggestions for troubleshooting this issue please let me know. Thanks.
