File Server Resource Manager

Applies To: Windows Server 2008

File Server Resource Manager (FSRM) is a suite of tools that enables administrators to understand, control, and manage the quantity and type of data stored on their servers. By using File Server Resource Manager, administrators can place quotas on folders and volumes, actively screen files, and generate comprehensive storage reports.

Managed Entities

The following is a list of the managed entities that are included in this managed entity:

Name Description

Quota Minifilter Driver

The quota minifilter driver intercepts file system calls and keeps track of storage usage for folders and volumes under quota management. It also enforces quotas by rejecting I/O requests that would cause a storage quota limit to be exceeded.

File Screening Minifilter Driver

The file screening minifilter driver intercepts file system calls and enforces file screening policies by rejecting I/O requests that would cause an unauthorized file to be saved on a folder or volume that is being screened.

FSRM Notification Service

The File Server Resource Manager (FSRM) service (SrmSvc) uses a Simple Mail Transfer Protocol (SMTP) server on your network to send e-mail notifications to users who exceed quota limits or attempt to save unauthorized files, or to system administrators, to alert them of quota or file screening violations. It can also send storage reports to system administrators and others who are interested.


The following is a list of all aspects that are part of this managed entity:

Name Description

FSRM Basic Functionality

File Server Resource Manager (FSRM) uses minifilter drivers to intercept the I/O requests that are sent to the volumes it manages. These minifilter drivers require configuration information from metadata files that are stored in each of the volumes that the minifilter drivers are attached to.

FSRM Import-Export and Configuration File Integrity

File Server Resource Manager (FSRM) includes command-line tools (Dirquota.exe, Filescrn.exe) that you can use for copying quota and file screen template settings from one computer to another. These command-line tools create import-export files in XML format. If one of these files becomes corrupted, File Server Resource Manager cannot import the file.

Also, File Server Resource Manager stores several configuration files in the System Volume Information folder of each volume that it manages. If any of those configuration files becomes corrupted, File Server Resource Manager will not be able to function properly.
