Hi, I am new to SCCM. I have cleaned up Active Directory by removing a number of Servers that are obsolete (Not in use and decommissioned) However, I find that the All Systems in SCCM is not updated accordingly. May I ask is there anything I have missed out ? Thanks

The All Systems collection will be update after 90 days. if you want it to happen fast deleted the computer from CM.

The cleanup in ConfigMgr will run based on the maintenance task schedule. Either you make the schedule aggressive or delete the objects from the console manually.

Hi @Garth Jones ,

May I ask 2 follow up questions ?

1) If "All Systems" will be updated after 90 days, does it mean that all other queries like "All Servers" will also be updated 90 days later ?

2) Does "All Systems" are updated via the "Active Directory System Discovery" Discovery Method ?

Thanks

Yes other collections will update after the computer is deleted from cm.

Kind of, it depends on if you are talking about adding or deleting.

From your reply, it appears that discovery method for Adding is different from Deleting ?

Could it be possible to elaborate ?

Thanks

It is the maintenance task that will delete old records.
