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?

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:
slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxxwhere
xxxxx-xxxxx-xxxxx-xxxxx-xxxxxis your product key.
Then try activating again.
