SQL4-00-016835 - SQL Server must have the Data Quality Services software component removed if it is unused.

Information

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default or selected for installation by an administrator, may not be necessary to support essential organizational operations (e.g., key missions, functions).

Applications must adhere to the principles of least functionality by providing only essential capabilities. Unused and unnecessary SQL Server components increase the number of available attack vectors. By minimizing the services and applications installed on the system, the number of potential vulnerabilities is reduced.

The Data Quality Services software component must be removed from SQL Server if it is unused.

Solution

Either using the Start menu or via the command 'control.exe', open the Windows Control Panel. Open Programs and Features. Double-click on Microsoft SQL Server 2014. In the dialog box that appears, select Remove. Wait for the Remove wizard to appear.

Select the relevant SQL Server instance; click Next.

Select Data Quality Services; click Next.

Follow the remaining prompts, to remove Data Quality Services from SQL Server.

Then run the following script:
USE master;
GO
DROP DATABASE DQS_STAGING;
GO
DROP DATABASE DQS_PROJECTS;
GO
DROP DATABASE DQS_MAIN;
GO

Restart the server.
