Hello everyone,
I am facing a very Odd issue for the past two days. one of our security groups that we have had for the past 3 years all of a sudden gets its membership rest and all members of the group gets deleted. after digging into the issue I found out that the membership gets deleted once you run gpupdate or every 90 minutes which means a GPO is causing it. but since the GPO is applied to OU level how it is only affecting one object? what can be the cause of this issue? can anyone plz let me know if you have any idea and solution for this.
