This is not what we need right now.
From the Micrsoft Sharepoint Team blog:
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.
We are working to release a hotfix to automatically fix this issue. A
manual work-around is currently available and involves customers
re-entering their Product ID number (PID) on the Convert License Type
page in Central Administration. For more information and detailed
steps please read this KB article.

Hopefully, MS comes out with a hotfix really soon.
