WinRM cannot process the request. An error occured while using the following authentication method: %1. Possible causes are:
  The user name or password specified are invalid.
  Kerberos is used when no authentication method and no user name are specified.
  Kerberos does not accept a local user name.
  The Service Principal Name (SPN) for the remote computer name and port does not exist.
  The client and remote computers are in different domains and there is no trust between the two domains.
 You may check the Event Viewer for events related to authentication.
 To continue using the same authentication method, check and resolve the issues above.
 To use a different authentication method, specify a valid user name and password and do one of the following: add the destination computer to the TrustedHosts configuration setting for WinRM or use HTTPS transport. You can get information about the WinRM configuration by running the following command: winrm help config.
