Running Win7 64bit, using windows firewall running on "private lan". I installed Tivo Desktop 2.8.2, it put all the "permits" in. I went an check the rules to make sure "private" was included in the policy. My Two Tivos, an old Series 2 single tuner and an S2 Dual tuner can't "see" it in my "Now Playing list". However if I disable Win7 firewall it shows up with no problems. I have tried using "Bonjour" & Tivo Becon. No change. Tried using Access Control "custom" and selecting my two Tivo units, nope. My Desktop is behind a firewall, so Win7 firewall really isn't "that" important, I could leave it off. But if there is something I am missing that needs to added to win7 firewall rules, please let me know. As stated before Tivo Desktop put all its services and .exe files into the w7 firewall with permits. Suggestions please..
