OKI, i'm pretty new to the whole network programming thing but i'm very
familiar with the framework. that being said, how do i go about creating a
TCP with a computer on a different network. i can create tcp connections on
machines within my olocal network with no problems either by DNS name or ip
address but as soon as i try to connect to a remote machine my program
cannot find them. this needs to be a tcp connection as apposed to http.

If you can ping the machine you should be able to connect to it using the
.Net Framework. Just do a Dns.Resolve.

C# sample that connects to the HTTP port of a server:

IPHostEntry serverHE = Dns.Resolve("servername");
IPEndPoint serverIP = new IPEndPoint(serverHE.AddressList[0], 80);

Socket client = new Socket(serverIP.AddressFamily, SocketType.Stream,
ProtocolType.Tcp);
client.Connect(serverIP);
