Well, props for fixing the problem. But the problem is Windows, not the TV.
I wonder what to take of this. Use Linux? Or at least set your home network as "Public" instead of "Private" (clearly a workaround, not a solution, because then (s)he would need to enable RDP on Public networks.
I'd say that the TV is to blame: it's claiming to be tens of thousands of different TVs, and Windows is dutifully keeping track of them and their configurations. Sure, Windows should be able to handle more devices on the home network than could fit within your average warehouse, but an issue like that should only crop up if you actually, y'know, try to do that.
