  2. Stop the File Replication Service from Services.msc
  3. Open Regedit and navigate to the below and change the BurFlags key to d2 in hex value
				
					HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup
				
			
  1. start the File Replication Service from Services.msc

 

PowerShell

  1. On the DC that is having issues with replication
  2. Open up PowerShell and copy the below commands
				
					Stop-Service ntfrs
$RegPath = "HKLM:\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup"
$RegKey = "BurFlags"
$RegValue = "d2"

Set-ItemProperty -Path $RegPath -Name $RegKey -Value "d2"
