PENDING New sccm site showing warning

[lalajee2018]

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

SQL and SCCM site server are running Windows 2019, everything is install on single server e.g. MP,DP,SUP

Check all of you server to make sure that NONE of them are windows Win2012. The logs will shows you EXACTLY which one trigger the warning.

Log show its the 2019 server which is showing as 2012 to pre check.

None of the sccm servers are 2012 including the old ones

This warning appears when you do a fresh installation of Configuration Manager. If you have delegated the site server computer account full control perms on System Management container in AD, you can ignore this warning and continue with installation.
