SP1 + Delete Aged Delete Detection Data Task
Have you also upgraded to Configuration Manager 2007 SP1 ? When you do this there will be a new Maintanance Task wich is called “Delete Aged Delete Detection Data Task” ! And then you think what does this do ? Today this task doesnt do anything, its for the future integration with future System Center Service Manager so you will have to bare untill ~2010 to use that.
