Could some one please give me some simple, network game example code. I have not been able to get anything working over our LAN. Any simple thing will do.

Run the following program twice, once as server and once as client.
When the PC requests the IP for the server app., it says you can leave the box empty, but you shouldn't. Instead, fill in your IP address.
To get your IP, goto start->run->cmd->type in 'ipconfig'.

Also, check out the code archives on this site. There's some useful networking code examples in there.

Sorry if this is something you have already looked at, but you may need to open the ports on a router and/or firewall too.
