As you can see from Figure 3 above, the quota limit for new users is greyed out. This is because we have already set it from the group policy, which overrides any customizable settings on the quota tab of a volume.
Whenever a user exceeds this limit a Warning event log will be written to the Application Event Log and shown in the Event Viewer. Figure 4: A warning event log for disk quotas. In the Quota Entries application however, it is correctly displayed as a Warning. When you press the Apply button on the Disk Quota Properties Dialog you are notified that the volume will be rescanned to update the statistics and that this operation may take several minutes.
Simply press OK to continue and have disk quotas enabled on that volume. From this section you can create, delete and manage quota entries for specific users or groups. If a user requires more space than others then you can set this from here. Choose a user from Active Directory and press OK. You will be given the option to limit disk space and set a warning level or not limit disk usage at all. Figure 5: Adding a new quota entry.
Once you have chosen your preferred settings, press OK and the user will be added to the list. Figure 6: Viewing a list of Quota Entries.

Setting a Group Policy The most practical means of configuring disk quotas on a large scale would be through a domain-level group policy. Windows Server brings together several MMC snap-ins and a handful of other features in the File Server Management console to help you manage your file servers. Managing a file server typically includes sharing folders, monitoring and controlling disk usage, monitoring open files, and backing up the documents and other files on the server.
The File Server Management console does all that plus a few other tasks. Here's a rundown of the tasks you can accomplish with this console:. The benefit to using the File Server Management console rather than Computer Management is that some additional file-server-related features are available in it, as well.
Let's take a look at each snap-in and those additional features. I won't cover them in detail, because it's likely that you are already familiar with at least some of them from the Computer Management console. Here you can view existing shares, sort the share listing by different criteria, add a new share, and remove an existing share. Note that in the details pane, several command links appear beside the shared folder list. These commands include:. The Sessions branch Figure E gives you quick access to the user sessions open on the server.
An open session does not necessarily equate to open files. This branch gives you an at-a-glance view of the users who are connected to the server and also gives you the capability to close a session. The Open Files branch Figure F gives you a list of the files that users have open on the server and the capability to close files either singly or all at once. Defragmenting a volume can improve disk performance and speed file access, as well as improve disk capacity.
The top frame of the Disk Defragmenter provides a volume list with statistics about the volumes, such as disk capacity and free space. The bottom frame provides a graphical look at the disk before and after defragmentation.
You can click Analyze to analyze the disk for fragmentation without actually defragmenting the disk, and click View Report to view fragmentation statistics Figure H. Click Defragment to start the defragmentation process. While the disk is being defragmented, you can click Pause or Stop to either suspend or stop the operation.
Defragmenting a volume does not require that you take a volume offline, remove shares, or otherwise make it unavailable to users. Defragmentation can take a long time, particularly on a large, active volume.
You can use the Disk Management console to create partitions, format volumes, set volume labels and other volume properties, change the drive letter assigned to the volume, mount a volume into an empty NTFS folder, convert basic disks to dynamic disks and vice-versa, and create volume sets and stripe sets.
If you right-click a volume and choose Properties, you'll see the screen shown in Figure J where you can access a variety of tools for managing the volume.
Table A summarizes common file management tasks and how to accomplish them through the File Server Management console:. What File Server Management Can Do Managing a file server typically includes sharing folders, monitoring and controlling disk usage, monitoring open files, and backing up the documents and other files on the server.
Here's a rundown of the tasks you can accomplish with this console: Manage shares - The Shares snap-in lets you view shares on the target computer, including hidden and system shares. You can add new shares and remove existing shares stop sharing their target folders. Manage sessions - When a user connects to the file server to access files, a session is created. You can view the current sessions on the target server and, if necessary, disconnect sessions singly or all at once.
Manage open files - You might occasionally need to view files that are open on the server and close selected files. For example, you might need to restart the server but first need to close all open files to prevent data loss. Or perhaps a user's system has hung and a file needs to be closed so it can be reopened. Then click Copy. In the Label text box, type an optional description that will appear next to any quotas derived from the template. A hard quota prevents users from saving files after the space limit is reached and generates notifications when the volume of data reaches each configured threshold.
A soft quota does not enforce the quota limit, but it generates all configured notifications. You can configure one or more optional threshold notifications for your quota template, as described in the procedure that follows. After you have selected all the quota template properties that you want to use, click OK to save the template. Quotas can also be created using the command-line tool dirquota.
