Service end

namespace WCFSample
{
[ServiceContract]
public interface IService1
{
    [OperationContract]
    string MyName(string name);
}
}

namespace WCFSample
{
public class Service1 : IService1
{
    public string MyName(string name)
    {
        return string.Format("My Name... {0}", name);
    }

}
}

namespace ConsoleApplication1
{
class Program
{
    static ServiceHost customerHost = null;

    static void Main(string[] args)
    {
        try
        {
            HostCustomerService();

            Console.WriteLine();
            Console.WriteLine("Press any key to stop the services.");
            Console.ReadKey();
        }

            catch (Exception ex)
        {
            Console.WriteLine(ex.Message);    
        }
        finally
        {
            customerHost.Close();
        }

    }

    private static void HostCustomerService()
    {
        customerHost = new ServiceHost(typeof
            (Service1));

        ServiceEndpoint tcpEndpoint = customerHost.AddServiceEndpoint(
            typeof(IService1), new NetTcpBinding(),
            "net.tcp://192.168.1.103:9020/Service1");

        customerHost.Open();

        Console.WriteLine("{0} {1}", tcpEndpoint.Address, tcpEndpoint.Name);
        Console.WriteLine();

    }
   }
  }

client end

namespace Client1
{
class Program
{
    static void Main(string[] args)
    {
        IService1 channel = null;

        var endPoint = new EndpointAddress(
             "net.tcp://192.168.1.103:9020/Service1");
       channel  = ChannelFactory<IService1>.CreateChannel(new NetTcpBinding(), endPoint);
       Console.WriteLine("Enter Name");
       string line = Console.ReadLine();
       Console.WriteLine(channel.MyName(line));
       Console.ReadKey();
    }

 }
 }

I think by default, NetTcpBinding requires a secure channel.

When you create your binding (on client and server), instead of:

new NetTcpBinding()

Try:

new NetTcpBinding(SecurityMode.None)
