Hello All! I have an interesting issue with my home setup. I have my iTunes library on a Mac Pro running Yosemite and the latest version of iTunes. Everything's up to date and iTunes is running all the time. I have 5 AppleTVs that connect, 4 of which are 3rd gens. The fifth is a 4th gen. All the AppleTVs are also up to date. The issue is that randomly but frequently one or more of the AppleTVs reports that is cannot connect to my library. Rebooting the AppleTV does not fix the issue. I have to quit iTunes on the Mac Pro and re-launch it and then the issue is resolved - for a little while. I have tried a number of steps to troubleshoot this including making sure that all the AppleTVs have direct access to the Airport Extreme (Gen 6, also up to date), first by connecting 3 of them wired and testing and then all 5 wirelessly, which is how they are set up now. For awhile I assumed it was one of the units "taking control" and making access to the library difficult. At first it seemed like it was always the Living Room unit so I swapped it with another unit on the network, both physically and name-wise. I figured that when the Living Room unit became the Office unit it would still control the system. But no! The "new" Living Room unit now assumed control. Which seemed particularly weird. Now they all have new, but random-ish names and I still have the issue. I've reset all the AppleTVs and have even gone to the step of replacing two of them under warranty and performing a DFU restore on the other 2 and still no success. Additionally I've rebuilt the iTunes library after performing a clean install of the OS. So, I'm out of ideas. Anyone else have any ideas?
