I have a customer who has a device acting as an AppleTV server which sometimes becomes unreachable by other devices. I checked and this device was in the users list rather than the servers list. We connected a laptop as a test and changed it from a user to a server, but again the device was still seen as a user rather than a server. I don't know much about Airplay and would apprectiate if anyone could help.
Controller is a 3600 running 6.4.2.4 with the default Airgroup settings.
