Note Because of file dependencies, the most recent fix that contains the previous files may also contain additional files.

STATUS

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

MORE INFORMATION

This update adds a new feature to the terminal client drive redirection that permits the OEM to filter access to files on the client.

One implementation scenario is to block access to all files in the \Windows directory of the client to help protect critical system files while you still permit users to access locally mounted storage media, such as the \Storage Card directory.

This update contains the following:
  • The filter-enabled update to the Terminal Service client
  • Sample source code to a filter driver
