Limit users space to a Home Directory

Quota Management is native in Windows 2000. Right click on any NTFS volume (that has a Drive Letter)-Properties - quota tab. When you first set up quota management you must allow the same disk space for all users, but once it is enabled you can change the amount on per user basis.
A good strategy is to use folder redirection in group policy to store all users data on one server, making quota management and backup easier to manage.

You cannot limit the disk space used by a user in a directory (like ?Home?). You will need third party software. However if you want to use disk quota you can do something smart like this:
- create a partition
- format it as NTFS (so you could enable disk quota)
- label it ?home? for example
- create all the users home directories in here
- use the drive for nothing else!!!
- enable quota for users
Now you have limits on users homes.
Hope this helps. I did this and it worked perfectly. Not to mention the additional safety added by security on a separate (logical) drive and safety added by the fact that it is a different partition that could break harder (loosing data will be improbable!!!).
