File Screening Minifilter Driver Integrity

Updated: January 27, 2011

Applies To: Windows Server 2008

For file screening enforcement to work, the file screening minifilter driver must be working properly, and it must be correctly attached to the volume. If the file screening minifilter driver is experiencing problems or is not correctly attached to the volume, users will be able to save unauthorized files.
