Microsoft Windows 2000 Server is the easy way to Internet-enable your business. As businesses come to rely more and more on the Internet, they have the opportunity to grow, extend their networks to partners and customers, and consider new ways to bring their products and services to market. To take advantage of these opportunities, businesses need an infrastructure that can readily respond to market forces, delivers high reliability, efficient management, ease of use, and supports the latest advances in networking hardware. And to readily pursue these opportunities, businesses want to build on their existing investments in skills and systems. Windows 2000 Server is designed to meet these needs for businesses of all sizes, from small, centralized organizations to the largest distributed enterprise. Building on the strengths of Windows NT Server 4.0, Windows 2000 Server sets a new standard for how well an operating system can be integrated with standards-based directory, Web, application, network, file and print services, powerful end-to-end management and reliability, to provide the best foundation for integrating your business with the Internet. The "Business Internet" starts here. Windows 2000 Service Pack 4 (SP4) provides the latest updates to the Windows 2000 operating systems. These updates are a collection of fixes in the following areas: security, application compatibility, operating system reliability, and setup. Windows 2000 SP4 is a recommended update that includes the updates contained in previous Windows 2000 service packs.
