When installing an additional SMS provider on a Site System Server there are some things that has to be checked so that a successful installation can be carried out.

If the additional SMS provider Server host any role that has SQL SRSS installed on it or any other SQL products, make sure to downgrade SQL Native Client to SQL 2008 if the SQL 2008 R2 version is installed. The method for fixing this is just an uninstallation via ARP and from the SCCM prereqs download folder can the MSI for SQLNCI be found.

The same prereqs has to be installed on the Provider Server as with a CM2012 SP1 Primary Site Server.
