Okay, this might be lengthy, as I've been on the phone with Tivo for the last couple of hours, but here goes (and please note that I've actually done all the things suggested in similar threads). My Tivo HD no longer sees my desktop computer -- sees my laptop and my wife's laptop just fine, but not my desktop. It used to, mind you, but would disappear every once in a while. Now it's been gone for weeks. The Tivo server was offline. When I tried to restart it, I got "An error has occurred." Red circle with a white X in it. That's it. No luck with support. Eventually, the guy decides I should try to use Tivo Beacon instead of Bonjour, even though I have the most current Bonjour. I somehow manage to get into the Server Properties (it's only happened once and I've been trying all day) and change it to use Beacon. I go into Services to start Beacon...Error: 1359. At this point, support decided it was a Windows issue and I should contact Microsoft. The problem is that my laptop is more or less the same as my desktop, and it runs fine, so I don't think it's a Windows issue. I made all the adjustments to my ports that I read elsewhere on here, but I have no idea if that's fixed anything as I can't get anything to start, because I still get the "Beacon Service is not running" message, and I can't turn it on because I get the Error: 1359 message. What's particularly frustrating about this is that I feel like switching to Beacon has just made this worse, and perhaps the port fix might have solved my original problem. Any ideas? Thank you!
