How do I troubleshoot Active Directory group membership replication issues?

1. Verify that the most recent synchronization has taken place for the domain to be inspected.
2. Identify the source of the changes to the group membership.
3. Check the replication status to identify any replication issues or conflicts with other domain controllers.
4. Perform a consistency check to identify any errors in the membership changes.
5. Verify the domain functionality.
6. Resolve issues detected during the consistency check.
