In Config Manager, virtualized and renamed computer not showing once original physical computer is renamed

Here is my issue.

I have a physical computer called name MyDesktop that is currently running and I can see in Config Manager. Using Disk2VHD I have created a virtual computer based on the physical computer. After virtualizing the computer, I turned off the physical computer and turned on the virtualized computer and renamed the computer to MyDesktop-VM. In the Active Directory and in Config Manager I now see the MyDesktop-VM system. Everything works great.

I need to also have the physical computer around for some time still so I un-joined the physical computer from Active Directory and then renamed the physical computer to MyDesktop-PHS and then re-joined the domain. All good.

In Active Directory I now see both systems, MyDesktop-VM and MyDesktop-PHS.

My problem is that Config Manager seems to be confusing the MyDesktop-VM and MyDesktop-PHS systems and I'm only seeing the MyDesktop-PHS system now. In one Device collection I can still see the MyDesktop-VM system. It appears that both systems still show the same MAC address.

What can I do to tell Config Manager to recognize these two computers as two different computers?

    Hi, @Nicholas Palmer

    Thank you for posting in Microsoft Q&A forum.

    It seems ConfigMgr think they are the duplicate hardware identifiers, you may try to configure these in hierarchy settings:

    • Set manually resolve conflicting records.
    • Add the MAC address to the list of duplicate hardware identifiers.
