I've searched here and on google for hours, but I can't see a fix for this. There are several posts with a problem similar than mine here, but went unresolved, or its resolutions don't apply in my case.
Using Itunes 10.1 and Comodo FW 5.0.16352.1142 (freshly downloaded and installed, default settings except for the rules you see on the screenshots), Itunes doesn't wanna discover shared itunes libraries from another computer. Both PCs (HP DV5t laptop and a desktop) are running Windows 7 64-bit. It seems anything related with Itunes that uses Bonjour is not working well (the ipod touch remote app doesn't discover the libraries either).
I have put all the relevant applications as trusted, and even have the firewall disabled. I don't get anything on the log or event viewer, even though I've set all blocking rules to log.
The moment I uninstall Comodo, Itunes and Bonjour work perfectly. I have uninstalled/installed Comodo firewall about 5 times, and I've also tried other free firewalls like ZoneAlarm (sucks), and a couple others whose names I forget, but none are as powerful as Comodo (don't let me filter by IP at least).
Any ideas would be appreciated!
