Try typing "ipconfig /flushdns", into your command promt. Then "ipconfig /release" and finally "ipconfig /renew".

Alternatively, you could just reset your Internet modem. For me, when I reset my modem, my ISP gives me a new IP address. Then I don't encounter the error anymore.

Strangely enough, the error -2146697211 is encountered on certain IP addresses that the server doesn't like.
