After installing windows 7 Ultimate on to two computers and having all types of trouble to get a network working correctly. I am networking 2 desktops and a laptop with XP and also have a media centre in the lounge room all conected by Ethernet cable. Under windows XP and the same configeration I had no problems. I would like to know what DRUGS the programers at Microsoft were on when they come up with this package. Why the *** they changed the networking setup to a homegroup witch has completly ruined a good system up. Cheers Brian
