I have been banging my head trying to figure out why my computers would not connect with the new installations of Win 7 (1 Desktop Win 7 x64 Pro, 1 Laptop Win 7 x64 Home Premium edition.)
I came across the setup software for our new Cisco E3000 Router and decided to re-install it.
It completed installation ok and then created the Easy Setup Key on a flash card. I took this to the other computer and BAM I now have computers on Networked, Homegroup and Printer shared!
It did not work on the XP machine though it says does not have permissions to enter Workgroup?
But in a few days I hope to install Win 7 x32 Pro on that machine
