The Allow Remote Shell Access machine setting should be configured correctly. Configures access to remote shells. If you enable this policy setting and set it to False, new remote shell connections will be rejected by the server. If you disable or do not configure this policy setting, new remote shell connections will be allowed. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Remote Shell\Allow Remote Shell Access (2) KEY: HKLM\Software\Policies\Microsoft\Windows\WinRM\Service\WinRS\AllowRemoteShellAccess
