After installing Windows Vista (including Business edition) or Windows Server 2008, the following error (see more Windows Vista activation error) may occur when user attempts to activate the new operating system installed, which causing the copy of Windows can’t be activated successfully.

Code: 0x8007232B
Description: DNS name does not exist.

The activation error happens even if user had entered a valid, legitimate and genuine product key. To avoid system from going into unusable state due to authenticated operating system (in the eye of Microsoft) with just a black screen, blinking cursor and not authentic Windows warning message on system tray (notification area), it’s important to fix the error and activate Windows within the activation grace period, which is the limited evaluation period given by Microsoft.

Although 0x8007232B error code carries the description of DNS name does not exist, however, the actual cause may not necessary related to DNS issue or activation server unreachable problem. In fact, the resolution to fix the error in order to activate the Windows Vista or Windows Server 2008 proper may be just as easy as changing the product key, where steps detail in guide below.

  1. Right click on Computer icon, and select Properties on the context menu. (Or go to Control Panel -> System and Maintenance -> System)
  2. Click on the link to Change Windows product key.
