Setting up WCF TCP service in a web application

Question

You have to generate the Proxy based on the metadata exposed over HTTP for tcp.(make sure httpGetEnabled is set to true). The address you use at the client should be the hosted address. Please refer the below post.

In your question you mentioned that you connected to "test.mydomain.com" but the error changed the server to "computername". Then in your comment you mentioned it still failing to connect. If you wish to have the alias returned in the WSDL/MEX Add the useRequestHeadersForMetadataAddress node in your service behavior. Here is the MSDN information on this node: MSDN useRequestHeadersForMetadataAddress node

This is how your config should look. This takes into account answer given by Prasath (httpGetEnabled="true").

<serviceBehaviors>
   <behavior name="ServerHubBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
      <useRequestHeadersForMetadataAddress>
         <defaultPorts>
            <add scheme="net.tcp" port="808" />
         </defaultPorts>
      </useRequestHeadersForMetadataAddress>
   </behavior>
</serviceBehaviors>
