Backup and restore of RID Flexible Single-Master Operations domain controller causes duplicate SIDs

This article has been archived. It is offered "as is" and will no longer be updated.
When you back up and then restore the Directory service on a relative ID (RID) operations master (also known as flexible single-master operations or FSMO) domain controller (DC), duplicate Security ID (SID) events may appear in Event Viewer.
This problem can occur when duplicate RIDs are created in the DC. After a RID flexible single-master operations DC is restored, it tries to check its RID flexible single-master operations ownership. But it returns TRUE even before init sync with another DC has finished. Because of this, when the RID flexible single-master operations DC is restored, it may use old RID pool values, and it can cause the restored RID flexible single-master operations DC to begin issuing duplicate SIDs.
