Quota Minifilter Driver Metadata Integrity

Updated: January 27, 2011

Applies To: Windows Server 2008

To enforce quotas, the quota minifilter driver uses configuration information that is stored in a metadata file. If there is a problem with this metadata file, the quota minifilter driver cannot attach to the volume, and users might be able to exceed their quota limits.
