The Dcdiag.exe VerifyReferences test fails on an RODC that is running Windows Server 2008 R2

Consider the following scenario:

• You have a domain that uses Distributed File System (DFS) replication to replicate the Domain System Volume (SYSVOL share).
• You prompt a member server that is running Windows Server 2008 R2 to a read-only domain controller (RODC) in the domain.
• You run the Dcdiag.exe utility on the RODC.

In this scenario, the VerifyReferences test fails. Additionally, the following message is logged:

Starting test: VerifyReferences
Some objects relating to the DC <DC name> have problems:
[1] Problem: Missing Expected Value
Base Object:
CN=<DC name>,OU=Domain Controllers,DC=<domain name>
Base Object Description: "DC Account Object"
Value Object Attribute Name: frsComputerReferenceBL
Value Object Description: "SYSVOL FRS Member Object"
Recommended Action: See Knowledge Base Article: Q312862
......................... 28-1205B710A failed test VerifyReferences

DFS replication creates the DFSR-LocalSettings object for the new RODC during the first restart after the promotion. Because the new RODC cannot create the object locally, the RODC targets any writable domain controllers to create the object and to set the msDFSR-Flags property. If the DFS replication service creates the object on a domain controller and then tries to set property of the object on another domain controller, the object is not replicated to this domain controller. Therefore, the setting operation fails, and this issue occurs.

To resolve this issue, install the hotfix on all Windows Server 20008 R2-based domain controllers in the affected domain.
