Most of us instinctively knew what the author meant and simply passed over the typo. But if "your" going to play Internet grammar Nazi, then you probably should know the difference between "your" and "you're," especially when offering unsolicited grammatical advice.

your vs. you're = English 101 :)

In other words, judge not, lest ye be judged...

Things have changed since this article was published. Not sure if this is peculiar to domain member machines or not, but on our Win 7 x64 machines, Windows tests connectivity by making an http connection to http://www.microsoft.com, then doing a DNS lookup to microsoft.com, then using an HTTP connection to the IP address returned, which is an address in the 134.170.0.0 block. The msftncsi.com lookups and http://www.msftncsi.com/ncsi.txt connection are no longer done. I have a few machines that are blocked from the Internet, so I had to allow http access to http://www.microsoft.com and to the entire 134.170.0.0 block to clear the connectivity test so the yellow caution would not show.

Android does the same thing - it checks "clients3.google.com"

Just put "127.0.0.1 clients3.google.com" as an extra line in your /system/etc/hosts file to kill it.

I’m running Windows 7/64. I’m trying to troubleshoot the Internet dropping out on me every 12 hours — I’m on Time Warner Roadrunner service and it literally stops working for 3 minutes every 12 hours, like clockwork. When the Internet drops, I see the little yellow (!) symbol over the network icon indicating I have no Internet connection, as you’d expect. Tonight I tried to log into my cable modem when this happened, to see if the signal strength was bad or whatever — couldn’t connect to it. Tried getting into the Vonage router, which is connected directly to the modem — couldn’t get in there either, until the Internet came back up. Is this a known behavior — that if Windows sees you have no Internet, trying to get to a LAN address like 192.168.0.1 doesn’t work either? I’ve seen this happen before on one of my other computers as well (Time Warner’s Internet drops out a lot for us occasionally).

Android can detect that "wifi needs authorization" when you connect to a public wifi, how does it do this?

It needs a separate lookup for http://www.msftncsi.com because it’s distributed through a CDN and the query response will be different depending on your location. The response for dns.msftncsi.com has only one answer. They’re not checking to see if DNS is working, they’re checking to see if they get the correct answer. Some captive portals will redirect HTTP traffic but will pass DNS requests to the Internet.
