I've been trying to set up HomeGroup in Windows 7 between my desktop and laptop. Both are Windows 7, one 32bit and one 64 bit, both running Bitdefender Internet Security. If I disable the firewall I can get the desktop to see the files on the laptop. With the firewall on they don't see each other at all. I'm not an expert at firewalls, but if I had some instructions I should be able to get it working. I'm guessing Bitdefender isn't Windows 7 friendly, because Microsoft said is should work with most firewalls. Thanks.
