A few days back, my Internet connection was giving me a lot of problems. For some reason it wasn’t opening this site, when it was able to open all the rest of the sites of the world :S. Then I came accross this site WhatIsMyIP. On this site I found some command lines to re-register my DNS connections. I used them and to my surprise, everything started working back :). I was able to access my blog. Below are the command lines I found from there. I hope they’ll be useful to you guys.
To open Command Prompt, click the “Start” button and then go to “All Programs”. Finally go to Accessories in the top, and click “Command Prompt". This will open Command Prompt where you can use the commands given below.
