Ok….. Enabled the le0 dhcp lookup again and lo and behold I see my iTunes Music Server again in iTunes!! Hurray!
Still my question remains if there is a way to “wipe the slate” as asked before?
I think the “right” thing to do is switch over to howl… the built-in responder is going to go away in favor of avahi and howl anyway, so now’s the time.
I think that’s the best solution.
