What is your model Apple TV (and OS version)? Identify your Apple TV model - Apple Support

What is your model computer (Mac or PC) and OS version?

Have you tried restarting all devices involved, including the router and optional other network gear?

I experiencing the exact same issue. Nothing changed with my windows computer running iTunes and nothing changed with my apple tv. One night it worked the next night it did not. I have re-set the apple tv, windows computer, and router. I've stopped home sharing on both iTunes and the Apple TV - nothing worked. Today, I total uninstalled iTunes on the Windows computer and re-installed it. Still The apple TV doesn't see the Library on iTunes.

Found this today, so now I know I'm not crazy. Hopefully someone can help solve this problem. I'm guessing an update from iTunes, Apple TV or Windows has caused this problem.
