This topic is intended to address a specific issue identified by a Best Practices Analyzer scan. You should apply the information in this topic only to computers that have had the Active Directory Domain Services Best Practices Analyzer run against them and are experiencing the issue addressed by this topic.

Issue

The domain controller cannot connect to the relative ID (RID) master in this domain.

Impact

When it runs out of the allocated set of RIDs, the domain controller will not be able to generate RIDs for new objects.

Resolution

Make sure that this domain controller is connected to the RID master in this domain.

Troubleshoot the domain controller that cannot connect to the RID master in the domain. If the issue is not identified and resolved, troubleshoot the domain controller that owns the RID operations master (also known as flexible single master operations or FSMO) role. For more information, see Responding to operations master failures (https://go.microsoft.com/fwlink/?LinkId=136715).
