DCDiag VerifyReferences test fails when you use DFSR to replicate SYSVOL
- You use the Distributed File System Replication (DFSR) service to replicate the SYSVOL folder.
- All domain controllers (DC) are running Windows Server 2008 R2 or a later version.
- You run the Domain Controller Diagnostics Tool (DCDiag) to generate a report about the replication.
The DCDiag report contains the following entry:
Problem: Missing Expected ValueBase Object: CN=<DCNAME>,OU=Domain Controllers,DC=<DOMAIN>,DC=<COM>Base Object Description: "DC Account Object"Value Object Attribute Name: frsComputerReferenceBLValue Object Description: "SYSVOL FRS Member Object"Recommended Action: See Knowledge Base Article: Q312862When this problem occurs, DCDiag validates the reference object for DFSR. Also, the NT File Replication Service (NTFRS) stops.
This logic is not included in earlier versions of DCDiag, such as DCDiag for Windows Server 2008 or DCDiag installed together with Windows Server 2003 Support Tools. Therefore, these versions search for the FRS member reference, and this generates a false error in DCDiag.
Alternatively, if the Windows Support Tools suite is installed on Windows Server 2008 R2, uninstall it. This resolves the problem and lets you run Dcdiag.exe from any location.
- Redirected phase: msDFSR-Flags on CN=dfsr-LocalSettings is 0x20 (32 dez)
- Eliminated phase: msDFSR-Flags on CN=dfsr-LocalSettings is 0x30 (48 dez)
In this case, DCDiag assumes falsely that the File Replication Service (FRS) is still configured for SYSVOL, and it tries to verify FRS objects and attributes in an Active Directory database that doesn't exist. Therefore, you can expect the verification to fail.
