DNS Error - Server cannot be found

I tried opening a particular website and i get this error: DNS Error - Server cannot be found

Is there a solution?

Go to Start/ Run/ type: cmd
Press Okay or Hit Enter.
At the command prompt, type or copy/paste: ipconfig /flushdns
Hit Enter.
Close the command box.

Then go to Start/ Control Panel, and choose Network Connections.
Right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and and choose Properties.
Double-click on the Internet Protocol (TCP/IP) item.
Select the radio button that says "Obtain DNS servers automatically".
Click OK twice to get out of the properties screen and restart your computer.
