Windows Security Log Event ID 684

684: Set ACLs of members in administrators groups

On this page

• Description of this event
• Field level details
• Examples

According to MS documentation: "Every 60 minutes on a domain controller a background thread searches all members of administrative groups (such as domain, enterprise, and schema administrators) and applies a fixed security descriptor on them. This event is logged."

I have confirmed this event to exist but it is unclear under exactly what circumstances it is logged.
