(2010-08-12) Restoring The SYSVOL (Non-)Authoritatively When Either Using NTFRS Or DFS-R (Part 2)

Posted by Jorge on 2010-08-12


This post focuses on restoring the SYSVOL when replicated through the NTFRS mechanism. For the previous post see here and for the next post see here.

SYSVOL Replicated Through NTFRS – Authoritative Restore – Steps To Take

To perform an authoritative restore of the SYSVOL when using NTFRS, use the following steps:

  • Start the Registry Editor
  • Navigate to "HKLM\System\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup"
  • Double-click on "BurFlags"
  • Assign it a value of D4 (hex) or 212 (dec)
  • Stop the NTFRS Service
  • Start the NTFRS Service

From the command-line the same can be achieved through:

  • REG ADD "HKLM\System\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup" /v BurFlags /t REG_DWORD /d 212 /f
  • NET STOP NTFRS
  • NET START NTFRS

As soon as the NTFRS Service starts, the following events appear with information about the non-authoritative restore.
