The Active Roles Administration Service fails to start. The Event Viewer logs show an error when attempting to connect to the Microsoft SQL Server host:
TCP Provider: An existing connection was forcibly closed by the remote host
When testing SQL Native Client connectivity in a .UDL file, the same error message is encountered.
Both the Active Roles Administration Service and the Microsoft SQL Server are hosted on Windows Server 2016.
This issue affects Active Roles 7.2.0 and Active Roles 7.2.1 only.
Install the latest version of the SQL Native Client from this Microsoft resource.
