I am running windows 7 home premium on my laptop and windows 7 pro on my desktop. I recently had to reset my laptop back to factory defaults. Before doing this my computer could connect to the home group on my desktop, now it doesn't even see the home group. I called the manufacturer of my laptop but they were worse than useless. they wanted be to contact someone else and pay for help when my computer is under warranty. Any help with this issue would be appreciated.
