question

Hi @bizcntradmin-7120,

You have posted in the System Center Operations Manager (SCOM) forum, since your issue is related to ConfigMgr/SCCM I suggest you ask over at the dedicated SCCM Site and Client Deployment forum by either posting a new question (thread) over here:
https://docs.microsoft.com/en-us/answers/topics/mem-cm-site-deployment.html

Or by changing the tag to the following: mem-cm-site-deployment

(If the reply was helpful please don't forget to upvote or accept as answer, thank you)

Best regards,
Leon
