That is right. In the past, often my iTunes would lose my AppleTV. After talking to Apple support, I tried restoring my AppleTv to its original state and that didn’t fix it. The same problem continued.
After debugging it for a while, Apple tech support sent me to Apple Store, where they replaced my AppleTv – I guess it was far cheaper for them to do that instead of debugging my network setup. (Not that I am complaining).
I came home and this problem recurred.
After a lot of debugging, it figures that whenever my iMac (iTunes server for my AppleTv) is connected through VPN to elsewhere, the iTunes – iMac network gets disrupted. Easily enough, disconnecting the VPN fixes the problem and reconnecting the VPN produces it again.
Not sure quite what the actual problem is, but so long as the primary iTunes server isn’t also on a different private network, everything else is hunky dory.
