Postup řešení
- 1 Press Windows key + R, type 'services.msc', and press Enter. Find the service that is failing. Right-click it, select 'Properties', and go to the 'Log On' tab. If the service uses 'This account', click 'Browse' to select the correct user, then enter the password twice. This ensures the service has valid credentials.
- 2 If the service uses 'Local System Account', switch to 'This account' and enter a valid account with appropriate permissions. Sometimes the built-in account lacks network permissions.
- 3 Check if the account is locked out or expired. Open Command Prompt as admin and run 'net user username' to see account status. If locked, unlock it with 'net user username /active:yes'.
- 4 Restart the service after updating credentials.
