Some of the Windows 8 builds I have done have produced this error when trying to active the software. 


Activation Error: Code 0x8007232b
DNS Name does not exist


The simple solution is below: 

  1. Open a Command prompt as Administrator
  2. At the command prompt, type the following command, and then press Enter:
  3. slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

if all goes as planned you will received a product key installed successfully message as shown below.
