cant't comunicate with service

Hi There,

I am writing an service that should be reply some information via TCP.
After starting the service a second PC try to connect with the service.

In the OnStart of the service I create an instance of my comunication class with:

string urlService = "net.tcp://";
host = new ServiceHost(typeof(ServicePCBI));
host.Opening += new EventHandler(host_Opening);
host.Opened += new EventHandler(host_Opened);
host.Closing += new EventHandler(host_Closing);
host.Closed += new EventHandler(host_Closed);
NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.None);
host.AddServiceEndpoint(typeof(IServiceTest), tcpBinding, urlService);

This part of code runs and listen to the port, I write an logfile to check all events and it looks like everything is ok.
I have checked the IP of the service (first I had an wrong IP, but was no big change to correct this).

Here one of the tests, that not work
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
IPAddress addr = IPAddress.Parse("");
IPEndPoint endpoint = new IPEndPoint(addr, 1234);
AddToLogFile("start listen! ");
while (true)
     Socket client = sock.Accept();
     AddToLogFile("Now ok! " + client.LocalEndPoint.ToString());

Has anyone an idea why I can't connect with the socket in the service?
