Endpoint Services, MECM, Avoid orphaned objects when importing a repurposed endpoint

Overview

Follow this guide to avoid orphaned computer objects when importing either a repurposed endpoint or an endpoint that has been offline for more than 90 days.

Systems

Microsoft Endpoint Configuration Manager (MECM), formerly SCCM

Intended Audience

University of Illinois IT Pros leveraging MECM, hosted by Technology Services' Endpoint Services team

Importing a repurposed endpoint (or an endpoint that was offline for more than 90 days)

  1. If the endpoint currently has Windows installed, keep the endpoint offline until this process is complete, or wipe the endpoint.
    1. If the endpoint cannot remain offline (i.e. endpoint is remote and may be turned on):
      1. Uninstall the MECM client - click here for a guide on uninstalling the client
      2. Or, disconnect the endpoint from the network until this process is complete

  2. Delete the endpoint's old AD and MECM objects
    1. Search for the MAC address or GUID at \Assets and Compliance\Overview\Devices in the MECM console

  3. Wait 15 minutes and import the computer information into MECM
    1. For units using a USB-to-Ethernet adapter for imaging multiple endpoints, import the endpoint's GUID information instead.  Click here for more information on how to identify an endpoint's GUID.
      1. EPS also recommends submitting a ticket to add the USB-to-Ethernet adapter as a duplicate hardware identifier, which prevents the adapter from being associated with MECM computer objects.  Repeatedly importing computer information with the adapter's MAC address can cause failed imports.

  4. Once the computer object is visible in MECM, PXE boot the endpoint directly into WinPE - do not boot into the OS

What causes an orphaned computer object?

Unit IT pros can only see computer objects that meet one of two rules:

  • Exists in your unit's Active Directory OU subtree
  • Device was imported via the console (connected to CAS), doesn’t have an MECM client installed, and matches the unit's computer name prefix query

Endpoints that are repurposed and turned on again (with its previous name and MECM client installed) fail to meet either rule. After being powered on, the MECM client re-registers with MECM infrastructure.  This creates an orphaned object that has no AD information, associates with the primary site instead of the CAS, and will not appear in the unit's all systems collection.
