Windows 2000 is based of the Windows NT Kernel and is sometimes referred to as Windows NT 5.0. Windows 2000 contains over 29 Million lines of code, mainly written in C++. 8 Million of those lines alone are written for drivers. Currently, Windows 2000 is by far one of the largest commercial projects ever built.
Windows 2000 is a line of operating systems produced by Microsoft for use on personal computers, business desktops, laptops, and servers. Released on 17 February 2000,it was the successor to Windows NT 4.0, and is the final release of Microsoft Windows to display the "Windows NT" designation. It was succeeded by Windows XP for desktop systems in October 2001 and Windows Server 2003 for servers in April 2003. Windows Me was released seven months after Windows 2000 and one year before Windows XP, but Windows Me was not intended to be, nor did it serve as the successor to Windows 2000. Windows Me was designed for home use, while Windows 2000 was designed for business.
Microsoft marketed Windows 2000 as the most secure Windows version ever, but it became the target of a number of high-profile virus attacks such as Code Red and Nimda.For ten years after its release, it continued to receive patches for security vulnerabilities nearly every month until reaching the end of its lifecycle on 13 July 2010.
Windows 2000 Professional Features:
- Support for FAT16, FAT32 and NTFS.
- Increased uptime of the system and significantly fewer OS reboot scenarios.
- Windows Installer tracks applications and recognizes and replaces missing components.
- Protects memory of individual apps and processes to avoid a single app bringing the system down.
- Encrypted File Systems protects sensitive data.
- Secure Virtual Private Networking (VPN) supports tunneling in to private LAN over public Internet.
- Personalized menus adapt to the way you work.
- Multilingual version allows for User Interface and help to switch, based on logon.
- Includes broader support for high-speed networking devices, including Native ATM and cable modems.
- Supports Universal Serial Bus (USB) and IEEE 1394 for greater bandwidth devices.
Windows 2000 Server Features:
- Active Directory improves manageability, enables security, and extends interoperability with other operating systems.
- Provides high-level interfaces for database access and Active Directory services.
- Lets you use COM+ to run component-based applications, integrated Web applications and message-queuing services.
- Transaction Services feature makes it easier to develop and deploy server-centric applications.
- Microsoft BackOffice is fully integrated into Windows 2000 Server.
Windows 2000 Advanced Server Features:
- The server operating system for e-commerce and line-of-business applications.
- Includes all the features of Windows 2000 Server, with additional scalability and clustering support.
- Increased reliability--ensure your business-critical applications are online when your customers need them.
- Easier to use and manage clusters, applications, and updates
- Supports 8-way symmetric multiprocessing (SMP) and up to 8 GB of memory (RAM).
Windows 2000 Editions:
- Windows 2000 Professional was designed as the desktop operating system for businesses and power users. It is the client version of Windows 2000. It offers greater security and stability than many of the previous Windows desktop operating systems.
- Windows 2000 Server SKUs share the same user interface with Windows 2000 Professional, but contain additional components for the computer to perform server roles and run infrastructure and application software. A significant new component introduced in the server SKUs is Active Directory, which is an enterprise-wide directory service based on LDAP. Additionally, Microsoft integrated Kerberos network authentication, replacing the often-criticised NTLM authentication system used in previous versions.
- Windows 2000 Advanced Server is a variant of Windows 2000 Server operating system designed for medium-to-large businesses. It offers clustering infrastructure for high availability and scalability of applications and services, including main memory support of up to 8 gigabytes (GB) on Physical Address Extension (PAE) systems and the ability to do 8-way SMP. It supports TCP/IP load balancing and enhanced two-node server clusters based on the Microsoft Cluster Server (MSCS) in Windows NT Server 4.0 Enterprise Edition.
- Windows 2000 Datacenter Server is a variant of Windows 2000 Server designed for large businesses that move large quantities of confidential or sensitive data frequently via a central server. Like Advanced Server, it supports clustering, failover and load balancing. Its minimum system requirements are normal, but it was designed to be capable of handing advanced, fault-tolerant and scalable hardware—for instance computers with up to 32 CPUs and 64 GBs RAM, with rigorous system testing and qualification, hardware partitioning, coordinated maintenance and change control. Limited number of copies of an IA-64 version, called Windows 2000 Datacenter Server, Limited Edition were made available via OEMs.
