After installing Windows 8 RTM Enterprise Edition when you try to activate Windows, you may see the following error message:
Error code: 0x8007232B
Error description: DNS name does not exist.
As you may expect, this error indicates that the key (a temporary key) cannot be activated. A new key needs to be set.
To change the key, open a command prompt as administrator. Move your mouse to the bottom left of the screen and right-click. Select “Command Prompt (Admin).”
slmgr.vbs /ipk <Key>
Go back and try to activate windows again. Windows 8 should activate successfully.
