Troubleshoot File Replication Service in Active Directory Domain Controller – Error 13508

Make sure non-PDC Domain Controller is sync the time with Domain Controller with PDC holder before we start to solve error 13508.

Steps of solution:

To fix the problem, you must designate a domain controller to be authoritative for the Sysvol replica set:

1. Stop the File Replication service on the PDC emulator FSMO role holder.
2. Use the Registry Editor to navigate to:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Paramaters\Backup/Restore\Process at Startup.
3. Double-click the BurFlagsValue Name, a REG_DWORD data type, and set the data value to D4, using the Hex radix.
   NOTE: If the BurFlags Value Name is set to D4 (authoritative) on more that one replica, conflicts and collisions will occur.
4. Exit the Registry Editor.
5. Start the File Replication service.
