I was just trying to play a game of Warcraft 3 over a Lan with a friend. He had recently upgraded to SP2 and his machine was running fine. When we tried to create a game we ran into a problem where I could see him create a game but he couldn't see me create on! Not only that but I couldn't koin the game he created. If I did try to join a game that he created my PB would completely freeze up. I couldn't force quit or anything. After several attempts to "fix" my mac I asked him if he had recently upgraded to SP2 when he said yes we checked his firewall and it was blocking Warcraft 3 from using some ports. Once we turned the firewall off we had no problems!! I am curious as to why windows firewall would cause my mac to crash and if this is a "special feature" in the eyes of MS? Also anyone else see anything about this?
