Everyone else in the SharePoint is posting this so I might as well too.
Microsoft has released an update for the SP2 Expiration date issue. The MS SharePoint Team Blog has information about it HERE.
I’ll be installing it soon in test and will let you know how it goes. In production, I’ll do the manual fix I’ll include below.
One other quick thing to note is that they say they will be incorporating the hotfix into SP2 within the next few weeks. If you have an SP2 download stored, be sure to grab the new bits once they are available.
An alternative to installing this update is to fix it manually:
- Click the Operations tab in Central Administration
- Go to Convert License Type
- Enter your product key and hit OK. That is all it takes. It will update on every server in your farm.
