Hi there,
Is it possible to force a task sequence to re-run when the advertisement is set to not re-run? Even when deleting the advertisement and recreating a new advertisement (which forces a new ID creation), somewhere in the workstation (be it WMI and/or registry) it knows that the task sequence (due to the same Package ID) has already run.
This guide is partially handy http://blogs.msdn.com/b/steverac/archive/2009/11/06/sccm-forcing-a-task-sequence-to-rerun.aspx
However, he does not mention how to do so with the advertisement set to not rerun - only 'always rerun program'
