Error Activating Windows 8

So, I installed Windows 8 and it never prompted me to enter my serial.

When I try to activate, I got "DNS name does not exist." with an error code  "0x8007232B"

To Activate Windows

1) Open Command Prompt with "Run as Administrator" option. You think this would be really easy, but with Microsoft way of thinking, not so !!

•   Go to Start Screen
•   Right click any where to get the  "All Apps" icon at the bottom of the screen
• Now locate command prompt icon, right click, choose "Run as Administrator" from the bottom

2) Now that you have the command prompt, type the following slmgr.vbs /ipk followed with your product key, as shown below


slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
