    Home-brew Your Own Instant Messenger App

    I am very new coding but have a strong background in Systems so I thought a messenger on my home network would be fun. I can get it to work when both the server and client run on the same machine but when I put the server on another box I get

    When I try to connect

    WinClient

    System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it at System.Net.Sockets.TcpClient.Connect(String hostname, Int32 port) at WinClient.Form1.btnSignIn_Click(Object sender, EventArgs e)

    What does this mean or where do I have to make changes to get it to connect either to my server box IP or DNS name? The port 500 is open and I even tried turning off the firewall on the server. It's Windows Server 2003 and my Client is Windows XP.
