I have set up Home network on a W7 Desktop. It connects with a wired connection to a Verizon Router/Internet connection. When I get the homenetwork code and take it to my Laptop, which connects wirelessly to the same router, and try to join the home network on the Desktop by entering the code from the desktop it cranks away for a minute and then gives me an error code "Windows cannot set up a Home group on this computer." Running the troubleshooter gives me no clue about what is wrong.
