I would believe that every SCCM Admin would at some point of time need to cleanup obsolete SCCM Client objects from the SCCM Sites.
Most of the time when this is needed, all you will be provided is a list of the machines that are no longer in Active Directory and these SCCM Clients has to be purged from SCCM.
For this purpose, the below VBS will do just that
