Tried all that, para, and you can "see" the computers on the network yet when you try to "join" it just goes "Password is incorrect".
Had *some* success. Took Avira off the netbook and disabled Comodo on same. Installed Microsoft Security Essentials and turned on Winders Firewall. Set up new home group. "Joined" group on desktop, etered password and it worked! But since I left Avira and Comodo running on the desktop I fail to see how that would be "blocking" since I can access shared files on desktop.............
I'm confused............
