Так. Спецально для тех, кто хоччет гаматься по сетке :
Playing on a LAN is just like playing on the internet with a few exceptions.
First, one computer must host the server, so follow the server side installation procedure to get it up and running.
Next, follow the client side installation procedure on any computers that will be joining the lan game, using the ip address of the computer running the server as the BnetD Server Address. Inotherwords, all computers will be connecting to the computer running the server, and the computer running the server will connect to itself.
Now heres the exception:
Where on internet servers it doesnt matter who creates the game within battle.net, when playing on a lan, the computer hosting the server cannot create the game. It will get stuck after you type in the game name and hit "create game". The buttons will all turn gray and nothing will happen. This is a bug.
To overcome this problem, simply have one of the computers that is _NOT_ running the server create the game, and the computer running the server can safely join in!
