New sccm site showing error

Question

Hi, I'm setting up new SCCM standalone site but i keep getting this warning.

error 1

The site server might be unable to publish to Active Directory. The computer account for the site server must have Full Control permissions to the System Management container in its Active Directory domain. You can ignore this warning if you have manually verified these permissions. For more information about your options to configure required permissions, see https://go.microsoft.com/fwlink/p/?LinkId=233190.

error 2

Support for Windows Server 2012 and 2012 R2 ends on October 9, 2023. Plan to upgrade your site servers to a supported operating system. For more information, see https://go.microsoft.com/fwlink/?linkid=2186091.

New SCCM server has full control on "System Management container" and its Windows 2019 Std

Answer 1

Are all servers e.g. DP, WSUS, RP, etc. all Windows 2019?

Answer 2

Hi, @lalajee

Thank you for posting in Microsoft Q&A forum.

For warning 1. Have you created system management container using ADSI tool like below article? And make sure the primary site server computer account be granted Full Control permissions to the System Management container and all its child objects.

For waning 2. I think it's just a warning, if you don't have a windows server 2012 and 2012 R2, you may ignore it.

Answer 4

Hi, @lalajee

You can delete System Management container if you no longer use the SCCM, if we still use it, we can only cleanup it.
