Error Code frs-err-authentication — Windows 11

Postup řešení

1. 1 Press Windows key + R, type 'cmd', and press Ctrl+Shift+Enter to open Command Prompt as administrator. This gives you the necessary privileges.
2. 2 First, check time synchronization: Type 'w32tm /query /status' and press Enter. If the time is off by more than 5 minutes, authentication will fail. To fix, type 'w32tm /resync' and press Enter. This forces the system to resync its clock with the time server.
3. 3 Next, verify DNS settings: Type 'nslookup [domain]' (replace [domain] with your domain name) and press Enter. If it fails, your DNS is misconfigured. Ensure the server's DNS points to the correct DNS server (usually the domain controller).
4. 4 Check the FRS service status: Type 'net start | findstr /i "File Replication"' and press Enter. If it's not running, start it by typing 'net start NtFrs' and press Enter.
5. 5 If the service is running but still failing, reset FRS: Type 'net stop NtFrs' and press Enter. Then type 'net start NtFrs' and press Enter. This restarts the service and may clear temporary issues.
6. 6 If the problem persists, you may need to perform a non-authoritative restore of FRS: This is advanced and requires careful steps. Type 'regedit' and navigate to HKLM\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters. Create a new DWORD value named 'Enable Journal Wrap Automatic Restore' and set it to 1. Then restart the server. This forces FRS to rebuild its database.
