I am a volunteer "system administrator" for a 500+ member computer club. We recently decided to set up a classroom trial of Windows 7 for the next year using 17computers, all about 4 1/2years old.(8 wireless, 9 wired - allconnected a6 year old Belkin wireless"G" router. I expected to encounter difficulties with more than 5 or 10 PC's, especially since my networking experience is minimal. I was pleasantly suprised to get the networking setup working well in an afternoon!

That's nice to know! By design, there's no limit to the number of computers that can join a HomeGroup.Steve Winograd MS-MVP (Windows Desktop Experience)
