Error Code error-logon-server-conflict — Windows 11

Postup řešení

1. 1 Open Command Prompt as Administrator (Win+X, then 'Terminal (Admin)'). We'll use nltest and gpupdate to fix.
2. 2 Check the secure channel: Type 'nltest /sc_query:yourdomain.com' and press Enter. Replace yourdomain.com with your domain. If it fails, the secure channel is broken.
3. 3 Reset the machine account password: Type 'netdom resetpwd /server: /userd:yourdomain.com\administrator /passwordd:*' and press Enter. Follow the prompts. This resets the password for the machine account, which often fixes the conflict.
4. 4 If netdom is not available, use PowerShell: Open PowerShell as Admin and run 'Reset-ComputerMachinePassword -Server -Credential (Get-Credential)'. This does the same thing.
5. 5 Force a group policy update: Type 'gpupdate /force' and press Enter. This refreshes policies that might be causing the conflict.
6. 6 Check DNS: Type 'ipconfig /flushdns' and 'ipconfig /registerdns' and press Enter. This clears and re-registers DNS records, which can resolve conflicts.
7. 7 If the issue persists, restart the Netlogon service: Type 'net stop netlogon' then 'net start netlogon' in an elevated command prompt. This restarts the service that handles logon authentication.
8. 8 If you're still having issues, check the event logs for detailed errors: Open Event Viewer (Win+R, type 'eventvwr.msc'), navigate to 'Windows Logs → System', and look for events with ID 568. The details will give more clues.
