The DiskQuota subkey contains entries that store Group Policy settings for disk quotas on NTFS volumes. These entries are created and maintained by Group Policy, and are read and interpreted by the Disk Quota program.
The Disk Quota policies included in Windows 2000 limit the amount of disk space users can consume, and they determine how the system responds when users exceed a warning level or quota limit.
Tip
For detailed information about particular Group Policy settings, see the Group Policy Reference (Gp.chm) on the Windows 2000 Resource Kit companion CD.
For general information about Group Policy, see Group Policy in Windows 2000 Help.
