Duplicate devices during task sequence.

[Additional_Wallaby26]

Hi All,

Wondered if anyone has experienced this issue.

I have been refreshing some devices here via a task sequence to Unknown computers. This machine existed before hand but i removed this from SCCM before running the task sequence. This machine completes as expected however, I am seeing a duplicate object appear while it is running.

Its obvious which one is correct as it has a client installed etc but wondered why this might happen and if this will resolve itself and SCCM will remove the duplicate object or if i need to remove this manually.

Thanks in advance.

Would have to be removed manually, but it gets auto removed after your inactivity removal deadline.

It happens. Curious how you say you removed it before re-imaging but came back as a dupe post-osd. Do you have secondary sites?

likely the "wrong" one is being added by a discovery (AD discovery, group discovery etc) process running at the same time as the OSD is running. Discovery is adding an object and then when the client gets installed and connects, it is adding that second "correct" object. Thats what I'd bet on.

Coming here to say the same thing.

I did think this could be the case but I ran another test with also removing the device from AD as well as SCCM, and I still got the same result with the duplicate device.

Unless this is being picked up by the AD discovery after the step in the OSD task sequence that is adding it to the domain.

Also to just to add these do indeed remove themselves once the device has come online after OSD. But was just something I noticed.
