Using a packet-sniffer, I've observed that my computer, when idle, receives a modest amount of UDP traffic. It's from a variety of IP addresses, and it all heads to port 50170. The originating ports vary; as far as I can tell, none of them are registered for any specific purpose. I thought that it might be DNS stuff, but it's not on port 53 and it's none of the ip addresses in question come up when I view my DNS table.
So what is it? Why are multiple computers sending me stuff over UDP on port 50170?
If you can't answer that, what sort of things can I do to find out?

It sounds like the traffic is being accepted, so I'm guessing that it's not blocked by any hardware or software firewall.
Is this definitely incoming (unsolicited) traffic? What are you observing it with?
If the traffic is happening, you can try a
netstat -b
to display which application is sending/receiving on which port.
You could also use a somewhat more sophisticated tool like TDIMon to see which process is generating or receiving the traffic... http://en.wikipedia.org/wiki/Packet_sniffer.
Which IP subnet(s) is it coming from?
If it's UDP traffic and a high port like that...well, it could be a game, or conversely, someone sniffing for a game server port. I don't think you've really provided enough information here to properly diagnose the problem, though.

The most common reason for, in the Windows OS, activity while idle through UDP traffic is applications that keep communication during idle for whatever reasons. This could be and IM applications or auto updating software or programs on your computer. This would include anything from Mozilla software to your Yahoo! chat application. Just because you have traffic does not mean that anyone is looking at your computer. Most likely it is your computer talking to the servers to do predetermined tasks at idle times. If you are worried about it there are many good firewall systems on the market that will allow you more control over these types of activity. Including Microsoft, McAfee, and Symantec just to name a few of the top ones.

try shields up from gibson research to see if you have open ports on your router

50170 is not specifically assigned - it is a dynamic port

Try running this -

The full program takes a long time to run, but it's pretty good, let it run overnight.
