    <p>I am new to WCF and stuck on a NET.TCP connection problem. </p> <p>Here's the setup. </p> <p>Server: Windows 8 Pro.</p> <p>Self-hosted WCF Service, using NetTcpBinding with SecurityMode.None:</p> <pre><code>try { _serviceHost = new ServiceHost(typeof(MouseTest)); _serviceHost.AddServiceEndpoint(typeof(IMouseTest), new NetTcpBinding(SecurityMode.None), "net.tcp://localhost:" + MyNetwork.Default.Port.ToString() + "/MyWPFServiceHost"); _serviceHost.CloseTimeout = new TimeSpan(0,0,5); _serviceHost.Open(); AddMessage("net.tcp open"); } catch (CommunicationException ce) { // MUST open visual studio as administrator!!!!! (Not this app, but actual VS2010. Console.WriteLine("An exception occurred: {0}", ce.Message); _serviceHost.Abort(); AddMessage(ce.Message); } catch (Exception ex) { AddMessage(ex.Message); } </code></pre> <p>Client machine (various types):</p> <pre><code>private void openTCPServiceButton_Click(object sender, RoutedEventArgs e) { String endpointAddress = "net.tcp://XX.XXX.XX.XX:" + MyNetwork.Default.Port.ToString() + "/MyWPFServiceHost"; if (channelFactory == null) channelFactory = new ChannelFactory&lt;IMouseTest&gt;(new NetTcpBinding(SecurityMode.None), new EndpointAddress(endpointAddress)); SendToListBox(channelFactory.Endpoint.Address.ToString()); try { proxy = channelFactory.CreateChannel(); proxy.StartRecording(); } catch (Exception ex) { AddMessageThreadSafe(ex.GetType().ToString() + ": " + ex.Message); } } </code></pre> <p>The service is hosted on my home machine, a Windows 8 box. When I connect from the same machine, all is well. From a different machine on the same LAN, all is well. From outside the LAN (on my office machine), I get:</p> <blockquote> <p>System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://xx.xxx.xx.xx:8085/MyWPFServiceHost. The connection attempt lasted for a time span of 00:00:01.1241124. TCP error code 10061: No connection could be made because the target machine actively refused it.</p> </blockquote> <p>Same error if I completely disable the Win8 firewall. </p> <p>If I run a copy of the service on a Windows Server 2008 machine at home, I can connect fine from anywhere, including over the internet.</p> <p>Please, after 3 days of this I am getting nowhere. Please also remember that this is SELF-HOSTED and not IIS hosted. Many thanks for any insight or where to start looking. I have made sure that all the services that are normally mentioned with this 10061 error are turned on.</p>

    1. COHave you checked `MyNetwork.Default.Port.ToString()` has same value(8085) on both the client and the service side?

    3. COPorts are the same number. And the XX's are just for my privacy here. As I said, the service works on a Server2008 machine, its just something about the Win8 box I can't figure out.
