    C# simple TCP Server/client problem

    Hi, I have a simple TCP server client in .net and for some reason the
    Accept() function in the Server part never gets called and never
    returns a new socket. This thing has been driving me nuts for days,
    here is the code please help if you can (the two machines that I am
    trying to connect are on a LAN Ethernet):

    Client()
    {
    Socket dcspTCPClient = null;

    try
    {
    dcspTCPClient = new Socket
    (AddressFamily. InterNetworkSoc ketType.Stream, ProtocolType.Tc p);

    IPAddress remoteIPAddress =
    (Dns.Resolve(st rHostName)).Add ressList[0];
    IPEndPoint serverIPEndPoin t = new
    IPEndPoint(remo teIPAddress,nSe rverPort);
    EndPoint serverEndPoint = (EndPoint)serve rIPEndPoint;

    dcspTCPClient.C onnect(serverEn dPoint);

    }
    catch (Exception error)
    {
    string strError = "TCPClient Error: "+error.ToStrin g();
    }

    }

    private Socket m_tcpServer;

    server()
    {
    try
    {
    IPEndPoint Ipep = new IPEndPoint(IPAd dress.Any, nPortListen);
    m_tcpServer = new Socket(AddressF amily.InterNetw ork,
    SocketType.Stre am, ProtocolType.Tc p);

    m_tcpServer.Bin d(Ipep);
    m_tcpServer.Lis ten(nClients);
    }
    while(true)
    {
    try
    {
    Socket sockAcceptClien t = m_tcpServer.Acc ept();

    if(sockAcceptCl ient.Connected)
    {
    ThreadPool.Queu eUserWorkItem(n ew
    WaitCallback(tc pMServerReceive Send), sockAcceptClien t);

    }
    }
    catch(SocketExc eption se)
    {
    string strSocketExepti on = se.ToString();
    }
    }
    }
    catch (SocketExceptio n se)
    {
    string strSock = "createTCPServe rMultithread error:
    "+se.ToString() ;
    }
    }

    It looks like it is connecting fine but Accept never gets called on
    the server side.
Working...
