Windows 7: Bonjour Service, Event 100 Application Error

Just thought I'd post here for any input before I slam Apple with this one. I presume its a DNS resolve error but I'm not sure where to go from here. None of my Apple devices (iPhone, iPad and AppleTV) will sync wirelessly with iTunes.

Here's the event viewer log:

I'm pretty sure this is a Windows firewall conflict. Since updating iTunes to iTunes 11 the TCP ports 123 and 3689 as well as UDP 123 and 5353 weren't showing as being open.

Quick tidy up of a few rules in windows firewall appears to have solved this. At least fingers crossed

Turns out I was wrong. Another similar error 100 displayed in event viewer.
