Hey everyone, this is my first post, but I have a major problem! I have the Doom 3 for PC with the latest patches and latest CO OP. I can play just fine online through the multi player option, but when my brother and I try to play through the LAN, we can't see each other on it! I will host a game, but it doesn't appear in my brother's LAN and so he can't join. If anyway can help me out and give any suggestions it would be greatly appreciated! I have spent countless hours trying to get us to play each other, but it's not working. I can join other people's servers just fine through the Internet option. I'm sure it is a network problem, but not sure exactly what. Even if I try to create an online server for him to join through the internet, he can't see my server. Any help would be appreciated! Thanks in advance!
