Hi People,

Due to the PCI requirement, I am forced to minimized the members of Domain Admins group.

This is including:
The SCCM client push install service account DOMAIN\SCCM-PUSH-SVC
The SCCM 2012 R2 Standard (Site Server) AD computer account itself PRODSCCM01-VM.

So I wonder what's the minimum service account that is recommended with bare minimum without breaking SCCM functionality ?
Can I remove the AD computer account from the Domain Admins group ?

My SCCM version is 2012 R2 or the vNext edition which I only use for Workstation only not the servers.

Thanks in advance.

SCCM Client push Install Account must be a local admin on computers. That means if you are pushing on domain controlers also, the account must be a member of Domain Admin group.

oh. And this is the only one that has to be a domain admin.

Hi Ben,

OK,if that's the case I can then put the DOMAIN\SCCM-PUSH-SVC as the Local Administrators on all Workstations only.

But what about the PRODSCCM01-VM AD computer account ?

You have A Computer Account (your SCCM Server) in domain admin group?

I can only say that our server computer account is not a member of domain admin group.

You have nothing to loos. You can remove the account from the group. Check that everything is ok, if not put it back again. And i think everything will work just fine.
