Unable to activate Windows 8 - 0x8007232B - DNS name does not exist.

So I finally decided to install Windows 8 on one of the work desktops and I could not activate it, I would get this error.

Error code: 0x8007232B
Error description: DNS name does not exist.

It turns out that because I had used the MSDN iso to install this machine I had to change the license as it seems that Windows 8 gets installed with a temporary key when using the MSDN isos.

In order to change the license, run the following command (from a command prompt or PowerShell) with elevated permissions (Run as Administrator):

slmgr.vbs /ipk mypro-ductk-key00-00000

Now Windows 8 can be activated.
