Obviously you will have searched on Google about this error, I assume?
From what I have read on a few different forums after copying and pasting that exact error is that it normally seems to be a Firewall problem more commonly Zonealarm, do you have Zonealarm?

- This blog also mentions the problem and that this user also has Zonealarm
I would suggest disabling your Firewall temporarily and trying connecting to Google or some form of News Website to see if you can get on with the Firewall turned off then I would suggest you should look through the Firewall Exceptions (Haven't used Zonealarm for over 6 months now so I can't help much on this, I dropped it because of weird problems like this, conflicting with programs etc).
Even better would be to uninstall Zonealarm if you have it? And use something like PC Tools Firewall Plus
it's free and I've heard good things about it and have been using it with my Vista Laptop for a week or so after I stopped using the bog standard Windows Firewall (I was pretty much alright with the Router Firewall and a Good knowledge on what I should keep away from)
