So, Windows 2000 does include the ability to set quotas on users, but with several limitations:

Windows 2000 only provides quotas assigned to a user at the volume level. When disk quotas are implemented on a Windows 2000 volume, all users are automatically assigned the same quota.
There is no ability to configure individual quotas on specified directories, allowing Windows 2000 to easily over quota the disk.
The only notification that a user will receive on reaching their quota limit is the "disk full" error - there are no custom messages or e-mails to instruct the user that they have reached the limit of their quota.
There are no milestones that will inform users of current quota status. The only action that Windows 2000 will perform is to write an entry into the event log.
Windows 2000 does not provide any reporting capabilities on disk usage.
Windows 2000 cannot run a command-line operation on reaching the quota limit.
Windows 2000 ignores compressed space, and quotas cannot be used on NT 4.0 or NT 3.51.
