Enables and disables disk quota management on all NTFS volumes of the computer, and prevents users from changing the setting. If you enable this setting, disk quota management is enabled, and users cannot disable it. If you disable the setting, disk quota management is disabled, and users cannot enable it. If this setting is not configured, disk quota management is disabled by default, but administrators can enable it. To prevent users from changing the setting while a setting is in effect, the system disables the Enable quota management option on the Quota tab of NTFS volumes. Note: This setting enables disk quota management but does not establish or enforce a particular disk quota limit. To specify a disk quota limit, use the Default quota limit and warning level setting. Otherwise, the system uses the physical space on the volume as the quota limit. Note: To enable or disable disk quota management without specifying a setting, in My Computer, right-click the name of an NTFS volume, click Properties, click the Quota tab, and then click the Enable quota management option. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Disk Quotas!Enable disk quotas (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\DiskQuota!Enable
