You may remember the high priority post back in May (Important information on SharePoint Server 2007 based products and SP2) about an issue with the state of activation after SP2 is installed on SharePoint Server and associated servers.  There was a pretty simple fix posted, but if you want to script the fix or just use the officially blessed correction to the issue, Hotfixes have been released for both the 64bit and 32bit versions of the SharePoint servers. 

You can find the 32 bit version at office2007-kb971620-fullfile-x86-glb.exe and the 64 bit version at office2007-kb971620-fullfile-x64-glb.exe


(Blogged for my reference and to close the loop on the follow up action with the release.)
