Group policies for disk quotas may not affect shared disks on a clustered server

A Group Policy that enables disk quotas on a shared disk on a clustered server may not function correctly.

After you enable the policy, when you view the properties of the drive on the Quota tab, you are unable to make any adjustments to the quota settings.

After you apply the policy, all check boxes on the Quota tab of the drive properties are not selected, and the quota policy is not in effect, even though you enabled it through the Group Policy Object. All local drives work correctly, only shared drives on a clustered server do not function correctly with quotas. However, you may expect this because the policy overrides any user-definable settings.

This behavior occurs because the Group Policy is applied to the computer before the clustered disks are brought online. Therefore, because the operating system is unable to access the drives when the Group Policy is applied, it is unable to affect these drives.

To correct this issue, you must set a policy to change the registration of the Group Policy extensions for Dskquota.dll. You need to make the following two policy changes to the disk quota policy processing:

1. Click to clear the Do not apply during periodic background processing check box to cause the disk quota policy to be applied as part of background policy processing.
2. Click to select the Process even if the Group Policy objects have not changed check box. Selecting this check box instructs the Group Policy engine to apply disk quotas any time a background policy is applied, even if the policy settings have not changed. In effect, this applies the policy periodically to drives that may have been previously unavailable to the operating system.

To make these changes, follow these steps:

1. Click Start, click Run, type gpedit.msc, and then click OK.
2. In the Group Policy window, expand Computer Configuration, expand Administrative Templates, expand System, and then double-click Group Policy.
3. Double-click Disk Quota policy processing, and then on the Policy tab, click to select Enable.
4. Click to clear the following two check boxes:
   • Allow processing across a slow network connection
   • Do not apply during periodic background processing
5. Click to select the Process even if the Group Policy objects have not changed check box, and then click OK.
