Hi Rick, What mdns issues are you seeing, and which version do you see it on? Has TAC been able to help?
mdns worked pretty good on 7.4.100.6 (engineering build) for us and we went to 7.4.110.0 and immediately added a new WLAN. Not sure if it was the new code or adding the WLAN, but on the new WLAN mdns is squirrely. Some AppleTVs don't work at all if you're on the new WLAN, and others do. But get on the old WLAN and it works fine. The settings on the new and old WLANs are identical. It's baffling. Anyone else see issues like this on 7.4?
