    what is mDNSResponder.?
    Hi was looking (playing around with) nortons firewall and found this thing that keep on connecting to the internet.

    what is it.?? and what does it do.?

    and more importantly, should I block it.??

    (jetting worried by these things that dont give me a clue as to what they are and do, after my ebay site was hacked, and someone listing an iPad on my ebay page.. freaked me out..)

    regards, Sandy

    The mDNSResponder.exe process belongs to the Bonjour for Windows service, which is Apple’s “Zero Configuration Networking” application, typically installed automatically by iTunes. If you’ve ever wondered how one iTunes install can talk to another on the same local network, Bonjour is what actually does this behind the scenes

    For the love of all that's holy, de-install that Norton piece of garbage and pray you got it all removed. And never speak of it again. And certainly don't ever buy anything with the word "Symantec" on it unless forced to at gunpoint.

    You are on a Mac now. You're safe enough already. No software firewall needed.

    Hey chas, we agree on something! But I thought guns were outlawed in Canada? Now if you were in Texas....

    Nope. It's just not as much of an issue.
