Chapter 1: Windows 2000 Architecture and Overview
Over the past few years, the world has been transformed by the proliferation of computing devices-from networks to handheld assistants-and the explosion of the Internet. Microsoft has endeavored to stay at the forefront of this tidal wave by producing ever more advanced operating systems to take advantage of the new technologies and provide users with the broadest range of resourceaccess capabilities possible. Microsoft's latest operating system manifestation is Windows 2000, which boasts the strengths of Windows NT and Windows 98, combined with many new technologies and features. This new network operating system offers a solid platform for building communication and informationdelivery systems of all sizes.
Windows 2000 Product Family
Microsoft has once again defined the standard against which all other operating systems are judged and all third-party vendors must compete. The Windows 2000 product family has four current members: Windows 2000 Professional, Windows 2000 Server, Windows 2000 Advanced Server, and Windows 2000 Datacenter Server. Although all are based on a common core, each version has specific features and components designed to support its unique purpose. Windows 2000 offers solid solutions for standalone systems and global networks alike.
Although Windows 2000 is the latest release from Microsoft, it is by no means the only or the last. Microsoft has definitive goals to provide full-featured operating systems for every computing device imaginable. Currently, Microsoft offers products for handheld devices to high-end server clusters (see Table 1.1).
Windows 2000 Professional
Windows 2000 Professional is designed primarily to serve as a client on a Windows 2000 network. However, it can also serve as a client on other networks, including Windows NT and NetWare, or it can function as a standalone system for isolated professional or personal home use. Windows 2000 Professional replaces Windows NT 4.0 Workstation as the network client of choice from Microsoft. This version of Windows 2000 is tuned to maximize performance for foreground applications and Internet resource access. It offers a platform rich in multimedia support (audio and video), full support for Internet standards, and an intuitive layout and control scheme, all without sacrificing high performance, reliability, and security control.
Windows 2000 Server
Windows 2000 Server is designed to function as a network server in a Windows 2000 domain. It can be deployed as a domain controller or a member server. As a domain controller, the first Windows 2000 Server in a network establishes the domain and its Active Directory. All subsequent Windows 2000 Server domain controllers become peers in supporting the domain and its Active Directory. As a member server, Windows 2000 Server can support a wide range of applications and services, including, but not limited to, file sharing, printer sharing, and Internet Information Services (IIS) hosting (Web, FI'P, email, and newsgroups). This version of Windows 2000 is tuned to maximize the performance of network services for a growing user base. It offers a stable platform for hosting network applications and sharing various resources (such as files, printers, and Internet access).
Windows 2000 Server was designed to create and support a primarily Windows 2000 network; however, it is backward compatible with Windows NT...
