Event ID 11 — Quota Minifilter Driver Integrity

  • Article

Applies To: Windows Server 2008 R2

For quota enforcement to work, the quota minifilter driver must be working properly, and it must be correctly attached to the volume. If the quota minifilter driver is experiencing problems, quota scans might fail, and updated quota usage information of volumes and folders will not be available. If the driver cannot attach to the volume, quotas cannot be enforced on that volume.
