Depending on the SQL Server component that is installed, you may not obtain all Microsoft SQL Server updates from Microsoft Update (MU) on a server that is running Microsoft SQL Server 2012 or Microsoft SQL Server 2012 Service Pack 1 (SP1) and that has SQL Server Master Data Service (MDS) installed. This issue occurs in either of the following scenarios:
- Scenario 1
The SQL Server MDS component is installed in an instance of SQL Server 2012 or SQL Server 2012 SP1 that does not have a SQL Server engine component installed. - Scenario 2
The SQL Server MDS component is added to an instance of SQL Server 2012 or SQL Server 2012 SP1 that has a SQL Server engine component installed, and the SQL Server engine already has the latest update that is offered by MU.
