Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)) in INetFwServices using NET_FW_SERVICE_REMOTE_DESKTOP type

    Question

  • I am trying to iterate within INetFwServices elements in Windows 10. However when I access to item Service Name: "Remote Desktop" Type: NET_FW_SERVICE_REMOTE_DESKTOP the application throws an exception Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)).

    The firewall.LocalPolicy.CurrentProfile.Services collection returns 3 items:
    1. File and Printer Sharing
    2. Network Discovery
    3. Remote Desktop

    When I read the third item "Remote Desktop" to get its GloballyOpenPorts occurred the error.

    In Windows 7 this type NET_FW_SERVICE_REMOTE_DESKTOP works correctly but in Windows 10 fails. How can I read the GloballyOpenPorts of Service Name: "Remote Desktop" in Windows 10?

    progID = Type.GetTypeFromProgID("HNetCfg.FwMgr");
                    firewall = Activator.CreateInstance(progID) as INetFwMgr;
                    ports = firewall.LocalPolicy.CurrentProfile.GloballyOpenPorts;
    
                    Debug.WriteLine("Count Services: " +  firewall.LocalPolicy.CurrentProfile.Services.Count);
    
                    foreach (INetFwService service in firewall.LocalPolicy.CurrentProfile.Services)
                    {
                        Debug.WriteLine("Service: " + service.Name);
                        
                        var port = service.GloballyOpenPorts;
                    }
