Resolving "DNS name does not exist" activating Windows 8?

I am trying to activate a new copy of Windows 8 Pro. When clicking on the Activate button in the Windows Activation screen comes back with:

DNS name does not exist

How can I go ahead an activate Windows 8?

Answer

Microosoft Knowledge Base 929826 article suggests it's looking for a KMS host server.

Make sure you're on (or VPNed into) your work or school campus when activating. If that doesn't apply to you there's a method listed on that article that shows how to use your MAK instead:

1. Run the command prompt as an administrator


2. Enter slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx where xxxxx-xxxxx-xxxxx-xxxxx-xxxxx is your product key.

Then try activating again.
