C# named pipes over a network

I'm trying to make an app that requires communication over a network. I was following the MSDN doc for named pipes here: http://msdn.microsoft.com/en-us/library/bb546085.aspx

I've tried the code from MSDN but no luck.

I saw that "." has to be replaced with the network name on the client side, which I did. I tried the network name and the server PC name but both failed to connect to the server (my laptop).

Now I'm not sure what to do – any advice? (The code below gets me "The network path was not found")

using System;
using System.IO;
using System.IO.Pipes;

class PipeClient
{
    static void Main(string[] args)
    {
        using (NamedPipeClientStream pipeClient =
            new NamedPipeClientStream("xxx.xxx.x.x", "testpipe", PipeDirection.InOut))
        {

            // Connect to the pipe or wait until the pipe is available.
            Console.Write("Attempting to connect to pipe...");
            pipeClient.Connect();

            Console.WriteLine("Connected to pipe.");
            Console.WriteLine("There are currently {0} pipe server instances open.",
               pipeClient.NumberOfServerInstances);
            using (StreamReader sr = new StreamReader(pipeClient))
            {
                // Display the read text to the console
                string temp;
                while ((temp = sr.ReadLine()) != null)
                {
                    Console.WriteLine("Received from server: {0}", temp);
                }
            }
        }
        Console.Write("Press Enter to continue...");
        Console.ReadLine();
    }
}
