Consider the following scenario:

  • Assume that you have a FileTable in Microsoft SQL Server.

  • You try to open a FileTable directory by using SSMS, File Explorer or Windows API.

  • When an application performs directory enumeration for the FileTable directory, the request call can be intercepted by a file system filter driver present in the client machine. The FileInformationClass request parameter can be changed to use FILE_ID_EXTD_DIR_INFORMATION instead. In this case, the client may receive an ERROR_FILE_NOT_FOUND (0x2) as a response from SQL Server.

In this situation, you may receive an error message that resembles the following on Windows:


"The File location cannot be opened. Either access is not enabled or you do not have permissions for the same."


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
