WCF Discovery finds endpoint but host is "localhost"

Question

I am trying to use the Discovery feature in WCF using http://msdn.microsoft.com/en-us/library/dd456783(v=VS.100).aspx as a starting point. It works fine on my machine, but then I wanted to run the service on a different machine. The service was discovered properly but the hostname of the found service is always "localhost" which is of course not much use.

Service Endpoint:

var endpointAddress = new EndpointAddress(new UriBuilder { Scheme = Uri.UriSchemeNetTcp, Port = port}.Uri);
var endpoint = new ServiceEndpoint(ContractDescription.GetContract(typeof(IServiceInterface)), new NetTcpBinding (), endpointAddress);

Client:

static EndpointAddress FindServiceAddress<T>()
{
  Stopwatch stopwatch = new Stopwatch();
  stopwatch.Start();
  DiscoveryClient discoveryClient = new DiscoveryClient(new UdpDiscoveryEndpoint());
  // Find  endpoints            
  FindResponse findResponse = discoveryClient.Find(new FindCriteria(typeof(T)));
  Console.WriteLine(string.Format("Searched for {0} seconds. Found {1} Endpoint(s).",stopwatch.ElapsedMilliseconds / 1000,findResponse.Endpoints.Count));
  if (findResponse.Endpoints.Count > 0)
  {
     return findResponse.Endpoints[0].Address;
  }
  return null;
 }

Should I simply set the Host to System.Environment.MachineName?

Answer 1

After doing some more searchingI have found no other solution than to use the System.Environment.MachineName

 new EndpointAddress(new UriBuilder {Scheme = Uri.UriSchemeNetTcp, Port = port, Host = System.Environment.MachineName}.Uri);
