Q: Apple TV can't find Computer

Hi,

I have 3 Apple TV's (3rd gen) on my network, all of a sudden 1 of them is failing to find my computer. There is no issue with my setup as the other 2 are finding my computer and if I play a movie on iTunes I can get it to stream to the Apple TV that can't find my computer.

All my ATV's and iMac are running the latest software, I have tried restarting and resetting my apple TV. No difference. Resetting has worked in the past when one of my other ATV's dropped out but not with this one.

Has anyone else had similar issues? Any suggestions would be great.

Thanks in advance
