Socket Client receiving multiple data

Hi All,

I have created a Client side socket Application that listens for messages from a server, and saves them into the database.
I've used Asynchronous client sockets to receive the text being sent from the server.
The problem i am facing appears that i am not receiving all the messages (serversends about 5-10 messages a second, whereby i reply with a message from the client back to the server. For each message the server sends, it is expecting a response back from the client and if no response was received in 15 seconds the server sends a second message to the client to inform no response was received. I am responding to all my messages from the client side but appears 2/10 messages i am missing the initial message from the server.
The basic code i used is similar to :

Any advise will be appreciated

Update:
I have also tried TCPClient, but having the same affect:

Int32 port = 7003;
              TcpClient client = new TcpClient("xxx.xxx.xxx.xxx", port);
              IPAddress ipAddress = System.Net.IPAddress.Parse("xxx.xxx.xxx.xxx");
              IPEndPoint remoteEP = new IPEndPoint(ipAddress, port);
              // Translate the passed message into ASCII and store it as a Byte array.
              Byte[] data = System.Text.Encoding.ASCII.GetBytes("connect1111");

              // Get a client stream for reading and writing.
              //  Stream stream = client.GetStream();
              NetworkStream stream = client.GetStream();

              // Send the message to the connected TcpServer.
              stream.Write(data, 0, data.Length);

              Console.WriteLine("Sent: {0}", "connect1111");

              // Receive the TcpServer.response.

              // Buffer to store the response bytes.
              data = new Byte[8192];

              // String to store the response ASCII representation.
              String responseData = String.Empty;
              while (true)
              {
                  // Read the first batch of the TcpServer response bytes.
                  Int32 bytes = stream.Read(data, 0, data.Length);
                  responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes);
                  Console.WriteLine("Received: {0}", responseData);
                  //*************************************
                  //Here i send a response back again using an unique code that was
                  //received
                  //*************************************
              }
