The Turn On Compatibility HTTPS Listener machine setting should be configured correctly. This policy setting enables or disables an HTTPS listener created for backward compatibility purposes in the Windows Remote Management (WinRM) service. When certain port 443 listeners are migrated to WinRM 2.0, the listener port number changes to 5986. A listener may be automatically created on port 443 to ensure backward compatibility. When this setting is enabled, this listener always appears. When this setting is disabled, this listener never appears. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Remote Management (WinRM)\WinRM Service\Turn On Compatibility HTTPS Listener (2) KEY: HKLM\Software\Policies\Microsoft\Windows\WinRM\Service\HttpsCompatibilityListener
