How to rebuild/recreate Active Directory SYSVOL and NETLOGON share… After domain controller migration from old to new you may face this problem..

Before you begin, keep a backup of SYSVOL & NETLOGON on working DC. Make sure to check the time settings between domain controllers.

Then open Registry editor (Regedit) and go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup path and modify BurFlags attribute value to D4

And Start File Replication Service

Now log in to problematic domain controller and stop the File Replication Service.

Go to “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup” path and modify BurFlags attribute and change the value to D2
