Remove Licensing issues in SharePoint Server 2007 post SP2

During the installation of SP2, a product expiration date is improperly activated. This means SharePoint will expire as though it was a trial installation 180 days after SP2 is deployed. The activation of the expiration date will not affect the normal function of SharePoint up until the expiration date passes. Furthermore, product expiration 180 days after SP2 installation will not affect customer’s data, configuration or application code but will render SharePoint inaccessible for end-users.

A fix is now available vide KB971620 - https://support.microsoft.com/kb/971620

note: Installation of this fix does not immediately change the license type. There is a background timer job that runs which normally takes about 20-30 minutes.

Note 1: We have also observed recently that in some scenarios entering the product key does not completely resolve licensing issues until and unless the PS Configuration wizard is run.
