I read through the thread and this is the Windows XP solution from John Nack.
For John Nack to say Bonjour only uses local servers is naive at best and disinformation at worst.
[Whoa--keep your shirt on. I'm passing along the information that's been provided to me by the Version Cue engineering team. If that's incomplete, I can gather more, but let's not get into suggeting that anyone is spreading disinformation. --J.]
Anyone who has Bonjour, as I have had, and a firewall can tell you that it requests access to the Internet. It is EASY to demonstrate. That, by definition, is not a "local" server. And, IMHO, is unacceptable. I control Internet access to and from my local network very tightly because of all the threats out there. Even if Bonjour is harmless, as others have said, it chews up cpu and memory, and Adobe has provided no reason that sounds vaguely acceptable for installing it on my machine without warning or notification.
BTW, turning off the process is not adequate. It can be removed, but the method is not real obvious. Here's how:
If using Windows XP...
start -> run -> type 'cmd' to bring up a command prompt
type 'sc stop "Bonjour Service"' (include the double quotes but not the single ones!)
type 'sc delete "Bonjour Service"'
Then go to the Bonjour folder and delete the .exe. There is also a dll that cannot be deleted. Change the name of the dll and reboot, and then delete it. AFter that, you need to run a free downloadable program called lspfix, because Bonjour fouls yet something else up that I don't completely understand, but the fix does, in fact, work. You may need Admin rights to do this; I'm not sure. BTW, deleting Bonjour has had no negative impact on my Adobe or ITunes apps that I have been able to discern; which raises yet MORE questions about why it is required in the first place.
Good luck and Just Say No to Bonjour.
