Do you have a firewall in any computer? mdns uses UDP port 5353 and that would need to be allowed for it to work. I've generally found mdns to be fairly unreliable, works sometimes and sometimes doesn't. Still, better to have it even as a flaky backup DNS than no DNS, if actual DNS has issues or is unreachable.
