Error Code rpc-s-cookie-auth-failed — Windows 11

Postup řešení

1. 1 Press Windows key + R, type 'cmd' and press Enter to open Command Prompt. First, check the system time on both machines by typing 'time' and 'date'. Ensure they are within a few minutes of each other. If not, adjust the time or configure time synchronization.
2. 2 To synchronize time automatically, press Win+I to open Settings, go to Time & Language > Date & time, and toggle on 'Set time automatically'. Also, ensure the time zone is correct.
3. 3 If time is correct, restart the RPC services. Press Win+R, type 'services.msc', and restart 'Remote Procedure Call (RPC)' and 'RPC Endpoint Mapper'. This clears any stale cookies.
4. 4 If the issue persists, clear the RPC cookie cache. In Command Prompt, run 'ipconfig /flushdns' to clear DNS cache, and then run 'net stop rpcss && net start rpcss' to restart the RPC service.
5. 5 Check for any security software that might be interfering with RPC. Temporarily disable third-party firewalls or antivirus and test the connection again.
6. 6 If you are in a domain, ensure that the Kerberos tickets are valid. Run 'klist' to view tickets, and 'klist purge' to clear them, then try again.
