I have both a laptop and desktop running Windows 7 Home Premium. I set up a workgroup on the desktop and joined the network from the laptop. I can see and access the laptop from the desktop but when I try to access the desktop from the laptop I an being asked for a user id and password. I did not create a password for the network. I have tried temporarily disabling the firewall on both machines with no change. I have run the wizard several times, on both machines, to find a problem and will usually get a message that homegroup information needs to be refreshed and it was fixed but the problem persists. Any Ideas?
