Consider the following scenario:

  • You install Windows Server 2012 R2 update 3000850 or 2975719¬†on a server that is running an instance of Microsoft SQL Server 2014 or 2016.

  • You create or use a FILESTREAM-enabled database.

  • The FILESTREAM-enabled database files are stored on a dynamic disk.

In this scenario, you may receive error messages that resemble the following:
