During the prerequisites check of SCCM 2012, you may encounter the error:
Configuration Manager Setup requires that the site server computer has administrative rights on the SQL Server and management point computers.
The prerequisite “Site server computer account administrative rights” equals the status “Failed”.
This message typically occurs when you’re setting up a new SCCM environment with a new remote SQL Database server.
In most cases, you can solve this error by adding the SCCM server name to the Local Administrators Server.
(To add a computer to the Administrators group, don’t forget to tick the Computers checkbox under Object Types , since you won’t find your server if you don’t :-) ).
When running SQL in a cluster, make sure to add the SCCM server to all cluster members.
If you’re installing SCCM 2012 with an account that’s not a member of the Domain Admins, make sure to add that user account as well to the Local Administrators group of the SQL Server.
