Why do I need mDNSResponder/howl?

[Randy]

The broadcast storm was coming from my hardware firewall/router, a 
D-Link box.  Apparently it didn't like mDNSResponder.  So technically it 
wasn't Fedora... but then again, it was.  Because I didn't have the 
problem before the service I didn't need was automatically installed and 
turned on.  :-)
