it actually is the lan fix downloadable on www.gamecopyworld.com modified so that the server shows up in the server list of the gamers. I only changed 1 letter, its weird they didnt do it already.

replace game.dll in your 2 directory with this one, be sure to back the original file up.
this patch is only needed server side

because hradba compares the client game.dll with the server one, people will get kicked for cheating
so turn hradba off
