FIX: Filestream directory is not visible after an AlwaysOn replica is restarted in SQL Server 2012 or 2014

Consider the following scenario:
  • You use AlwaysOn Availability Groups together with FileTables in an instance of Microsoft SQL Server 2012 or 2014.
  • You enable the FILESTREAM for file I/O access option on the replicas.
  • You restart a replica, and you set the replica as the primary replica after the restart.

In this scenario, the Filestream directory is not visible in Windows Explorer. However, you can still access the Filestream directory by using its full path.

For example, you can open a Filestream directory by using a full path similar to \\listener_name\mssqlserver\filetable_directory. However, if you browse to \\listener_name\mssqlserver, the filetable_directory folder is not visible.
The issue was first fixed in the following cumulative update or Service Pack for SQL Server.

 Cumulative Update 3 for SQL Server 2012 Service Pack 3.
