Windows 2000 Server file management features improve resource availability, and make it easier to manage your network storage requirements. Security features in Windows 2000 Server provide the highest levels of data protection, and simplify administrative tasks.

File Management Enhancements
Windows 2000 Server provides significant enhancements to file management capabilities, enabling you to implement a more secure and manageable network. Enhancements to file management in Windows 2000 Server include:
- Distributed File System (DFS). Simplifies the process of creating a single directory tree that includes multiple file servers and shared folders in a group, division, or enterprise. This structure makes it easier for users to find and manage data on a network.
- Disk quotas. Provide more precise control of network-based storage. You can use disk quotas to monitor and limit disk space use, increasing bandwidth efficiency.

Security Features
Windows 2000 Server contains all of the same security features as Windows 2000 Professional, plus the following features:
- Active Directory security. Allows administrators to create group accounts to more efficiently manage system security, by allowing access to objects in Active Directory based on group membership.
- Security Templates. Organizes all existing security attributes into one place, making it easier to administer security on a local computer.
- Security Configuration and Analysis. Allows you to import one or more saved configurations to a security database. Importing configurations builds a computer-specific security database that stores a composite configuration.
