Hello MsTech,
This sounds like a common issue after you restore a DC, and it forces authoritative synchronization.
Please check this document that explains the checklist and troubleshooting: https://learn.microsoft.com/en-us/troubleshoot/windows-server/group-policy/missing-sysvol-and-netlogon-shares
Initially I would try the next:
- Open the registry and navigate to "HKLM\System\CurrentControlSet\Services\NtFrs\Parameters"
- Change value for "Enable Journal Wrap Automatic Restore" from 0 to 1. If the DWORD Value does not exist, create a new one, including spaces but without the quotes.
- Stop the NTFRS Service (from an elevated command prompt and type "net stop ntfrs")
- Start the NTFRS Service (net start ntfrs)
- Check for File Replication Services events in Event Viewer:
• 13553 – The DC is performing the recovery process.
• 13554 – The DC is ready to pull the replica from another DC.
• 13516 - If you receive this Event ID everything went fine, then you can continue: - From the elevated command prompt type: "net share" and look for SYSVOL and NETLOGON. The issue will be resolved when the new SYSVOL replica from a peer Domain Controller. This may take some minutes.
- Revert the value for "Enable Journal Wrap Automatic Restore" from 1 to 0.
Hope this helps in your case,
Best regards,
