Event ID 12 — 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.

Event Details

Product: Windows Operating System
ID: 12
Source: datascrn
Version: 6.0
Message: The screening minifilter driver was successfully attached to volume "%2 (%3)" and has received file screen and file group definitions from the File Server Resource Manager service after a longer than expected delay. File screens will now be enforced on the volume and notifications will be raised when blocked files are detected. The delay is most likely a result of the machine experiencing heavy load.


This is a normal condition. No further action is required.
