sending xml request via TCPClient takes long to receive response.

Good day guys,

i have a problem where im trying to connect to a host using the ip address provided, but i cant seem to be able to get a response from it.

    try
                {
                    Socket serverSock = new Socket(
                 AddressFamily.InterNetwork,
                 SocketType.Stream,
                 ProtocolType.Tcp);


    IPAddress serverIP = IPAddress.Parse("");
                  IPEndPoint serverEP = new IPEndPoint(serverIP, port);
         Byte[] data = System.Text.Encoding.ASCII.GetBytes(postData);



                    NetworkStream stream = client.GetStream();

                    stream.Write(data, 0, data.Length);

                    Console.WriteLine("Sent: {0}", postData);

                    data = new Byte[256];

                    String responseData = String.Empty;


   SocketPermission perm = new SocketPermission(NetworkAccess.Accept, TransportType.Tcp, "", port);
                    Int32 bytes = stream.Read(data, 0, data.Length);
                    responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
                    Console.WriteLine("Received: {0}", responseData);


                    stream.Close();
                    client.Close(); 

   }
                catch (Exception)
                {

                    throw;
                }     

after that i will capture the response and load it into xml document. But im not receiving any response at all. it as it its hanging...

kind regards

Tony
