First of all, I have 7 up and running fine, thanks for all the great info here. I have 2 other computers at home, one running xp professional, and one running xp home. When I first set everything up last night I was able to access them all from the new machine running windows 7. Today, when I tried to connect neither of the xp machines would show up on the new machine, they could see each other fine, but not the new machine. I tried most everything I could think of, rebooting all the computers, rebooting the router, turning off the firewalls, and running the trouble shooter, all to no avail. Any thoughts on how to fix this would be greatly appreciated, and sorry for the newbie type question, but, well I'm old.
