I've just installed the 7057 build of Win 7 beta and I gotta say the networking changes they have made between build 7000 to 7057 really
it's taken me 3 days of tearing my hair out frustration to get Win 7 to see my wifes Win Xp Pro computer, what ever M$ did they really screwed up on the changes. They have implemented a new thing called Homegroups but that can only be used between Win 7 Computers, if you go through the normal process of trying to set up a network with a XP machine on it forget about it you can ping the machine but not see it.
Other than that I finally have SH3 running on Win 7 after finding a Budget version of SH3 with no Starforce protection.
