The PEAUTH service is a kernel device driver. In Windows 8 it is starting automatically during the operating system startup. If PEAUTH fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the PEAUTH service hasn't been started.
