Well, i decided to try out vista, so i partitioned off thirty gigs of my hard drive and gave it a go. The weird thing is, now vista has found all of theses other computers, and "xbox 360 extensions", and I'm not on a LAN. I'm using cable internet connected directly into my modem, into the wall. I can literally play music from other peoples computers. This doesn't seem safe. In XP, the my network places shows no other workgroup computers. I'm stumped as to where they are coming from. Bad isp?
