sudo discoveryutil mdnsactivedirectory yes

Seems to have the desired effect. I am not exactly sure what it does, so use at your own risk. And I will bet it will not survive a reboot, but it looks like a start.

I got it from this thread https://discussions.apple.com/thread/6611817

Do check and revert.

@ocodo Thanks... Yes I did. As mentioned above, loading/unloading the discoverid plist only brings brief respite.

Unfortunately you may also be right in your general comment about AirPort. My solution only lasted for about a day. Today all .local boxes are back to nowhere. :-(

My apologies to all those that I sent on a wild chase for ethernet cables. Does anybody know how to delete a posting :-) ?
