Stop FRS
Start Registry Editor (Regedt32.exe)
Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
NtFrs\Parameters\Backup\Restore\Process at Startup
On the Edit menu, click Add Value , and then add the
following registry value:
Value name: BurFlags
Data type: REG_DWORD
Radix: Hexadecimal
Value data: D2
Quit Registry Editor
Restart FRS
Fix Journal Wrap
Click on Start, Run and type regedit
Expand HKEY_LOCAL_MACHINE.
Click down the key path:
“System\CurrentControlSet\Services\NtFrs\Parameters”
Double click on the value name
“Enable Journal Wrap Automatic Restore”
and update the value
If the value name(Enable Journal Wrap Automatic Restore) is
not present you may add it with the New->DWORD Value and set the value to 1
and restart FRS service
Once the recovery is completed make sure that the Enable Journal Wrap Automatic
Restore is set to 0 or delete the key
Normally for an Authoritative Restore you stop at NTFRS
services on all DCs
Set burflags to D4 on a known good sysvol (or at this time restore sysvol
data from backup then set burflags to D4) then start NTFRS on this server You
may want to rename the old folders with .old extensions prior to restoring good
data
Clean up the folders on all the remaining servers (Policies Scripts etc) –
renamed them with .old extensions
Set burflags to D2 on all remaining servers and start NTFRS
Wait for FRS to replicate
Clean up the old stuff if things look good
