I've installed two appleTV in a remote building at our facility. There are three switches and the last one being wireless that connect the two ATV. Once moving the ATV from my office (test) area to the new area they have lost connection to iTunes on my PC (the PC doesn't see them and they don't really see the PC if you try to reconnect them). I then took my ipad to that location and cannot get VNC (bonjour) to see my desktop iMac! So I've concluded that bonjour (assuming ATVs work on this protocol too) is not transmitting over my switches. 1. These are switches and not firewalls 2. All other protocols work across this same path Any ideas?
