NT 5 will support this. Until then:

Here's the answer I received from Jose Almeida to a similar question:

>>>>>>>>>>>>>>
I did not found anything regarding the space limitation on NT by user like we have in Novell, but I found a Tecnet
note about quota manager that is the product that is usualy used to do this.

How to use disk space quota management to reduce hard-to-measure network management costs.

Overview
The personal computer put power in the hands of non-technical computer users, and they’re not ready to give it
up any time soon. However, when it comes to installation, training, trouble-shooting, and maintenance, many end
users turn to their corporate information technology (IT) support services to supply the necessary expertise.
Clearly it’s efficient for an IT group to develop server-based network management support. Backup, security,
and maintenance procedures can be put in place for each server on the network. But concentration of power in a
server machine used by multiple clients brings its own maintenance and management problems, such as allocating
and managing space for all the users who share the system. Setting and enforcing disk quotas, or quota
management, is one solution to potential server disk space management problems.
Demands on Network Administrators Are Increasing
Disk space management is only a fraction of a network administrator’s job: in today’s environment, admins
provide local and wide area network connectivity, manage hardware and software inventory, installation,
upgrades, and training, and are on the front line for troubleshooting and help desk support.
The last thing an administrator needs is to have a server shut down due to a single user filling up a disk partition.
The next-to-the-last thing administrators want to do is police users to clean up directories and delete or archive
files no longer in use.
Network managers are looking more and more to “smart” network management utilities that let the system
enforce administrative requirements, policies, and procedures. Quota Manager helps system administrators, in
real time, control the cost of running their networks by letting the system manage itself, 24 hours a day, seven
days a week.
Experienced Administrators Know the Value of Quota Management
Some form of disk space quota management has been available for computers ever since the early time-sharing
systems let users directly access computing resources. Experienced system administrators who have managed
older, proprietary network operating systems expect some sort of quota management for Windows NT — and
Quota Manager integrates with Windows NT security, event logging, registry, and automated NT Services to fill
the need in the NT environment today.
Quota management is one of the simplest network management support strategies around: you allocate a fixed
amount of space on a machine’s hard disk for specific file operations accessible to privileged users. You warn
users when they approach the limit of their allocation, or quota. Users who need more room either delete files or
request an increase or a temporary suspension (Grace Period) of their quota from their system administrator. The
object of the game is to avoid filling up a partition on a disk, which could cause two potential problems: 1)
Downtime of critical operations and 2) Excessive disk fragmentation as the last files are written to smaller and
smaller contiguous blocks.
Quota Management Protects System Resources and Saves Money
Most servers aren’t just end-user file servers any longer. Many are also accessed by external systems and fed
electronic mail, news feeds, downloaded files, and many other operations in an increasingly inter-networked
world. Administrators may now set and change default setting on multiple objects quota at the same time.
Therefore, system administrators can protect their servers by managing quotas in a number of areas:
· User Directories: the obvious target for quota management is the home directories of end users. Quota
management places the responsibility for file cleanup in the owners’ hands, removing the system administrator
from the watchdog position.
· Public Directories: more team-oriented software products (groupware, workflow apps) require increased use of
shared directories. Quotas help keep these areas from growing out of control when no one person feels
ownership.
· Mail Directories and Files: it’s no longer uncommon for some users to receive dozens (sometimes hundreds!) of
mail messages per day. Quotas help keep your servers from becoming expensive post office archival stations.
· Batch Servers: Servers that are set up as batch servers to run overnight or during non-peak hours are often not
closely administered during that time. Quotas help keep runaway batch jobs from filling a server up entirely and
bringing it down for hours before someone has a chance to reboot.
· Download Areas: Mainframe downloads, and file transfers from remote sites or commercial on-line services eat
up file space quickly. Use quotas to encourage users to keep these downloaded files moving from this temporary
space into their intended location.

NTP's Quota Manager for Windows NT
New Technology Partners currently ships Quota Manager for Windows NT. Integrated with the Windows NT
file system (NTFS) it lets system administrators set limits on the maximum size of files and directories. Quotas
may also be set on shares in NTFS, FAT and HPFS partitions. Once quotas are set, Quota Manager
automatically sends information directly to network users as they reach the upper limits of the quotas. Network
users respond by adding, modifying, or deleting files and managing directory sizes to stay within their preset limits.
On the Client and the Server
Quota Manager is designed for a client/server network. On the server, Quota Manager runs as a Windows NT
Service monitoring disk objects, preventing growth over quotas, and sending information to network users and
administrators.
On the client, Quota Manager provides an Administrative User Interface that ships in a 32 bit version for
Windows NT and Windows 95 as well as a 16 bit version compatible with Windows for Workgroups. The
Administration Client provides quota configuration, management, and remote administration capabilities to system
administrators.
For users, Quota Manager is now shipped with the Inquiry Tool, which allows users to view information about
quotas set on objects that they have access to. This important feature allows users to self manage, and be fully
aware of disk space limitations.
Quota Manager in Action:
· Your system administrator uses the Administration Utility to set a quota on a network user’s home directory.
The directory is currently approaching the “quota,” its allotted disk space.
· A warning is sent to the user and the administrator indicating that the directory is approaching its quota.
· When the network user attempts to copy a new file into the home directory on the server, Quota Manager
allows the complete file transfer, even if the file size causes the directory to exceed the set quota.
· When Quota Manager receives information from Windows NT that the directory is over quota, Quota Manager
sends a message to the network user and the system administrator, updates the Administration Utility, and sends
a notification of the event to the Windows NT Event Log.
· Quota Manager then changes the access control list of the directory to deny the creation of new disk objects or
to add to any existing objects in that directory.
· There are now a few choices that the network administrator has. If no action is taken by the administrator, the
object remains locked until the user moves files out of the directory or otherwise manages the directory to bring
the size back under quota.
· Network users who require changes to their quotas on files and directories may request the system
administrator to modify quotas through use of the Administration Utility. Administrators may also choose the
“Unlock with Grace” option, the lock on the Quota is suspended for a set amount of time while the user makes
the necessary changes to the object.

New Features in Version 2.0
New Technology Partners has been actively supporting and enhancing Quota Manager since its first release.
Version 2.0 offers a host of advanced features and benefits to the system administrator and an improved, more
flexible administrators interface. Behind the scenes the Administration Client and the Version 2.0 Quota Manager
Service communicate faster and more efficiently.
This new release also allows for an optional Application Programmers Interface (API) that makes Quota
Manager callable from the Windows applications. Now you can integrate quota management administrative
functions into your favorite system management utilities.
