'''Windows 2000 Professional''' was designed as the desktop operating system for businesses and [[power user]]s. It is the client version of Windows 2000. It offers greater security and stability than many of the previous Windows desktop operating systems. It supports up to two [[central processing unit|processors]], and can address up to 4{{nbsp}}[[Gigabyte|GB]] of [[Random-access memory|RAM]]. The system requirements are a Pentium processor (or equivalent) of 133{{nbsp}}MHz or greater, at least 32{{nbsp}}MB of RAM, 650{{nbsp}}MB of hard drive space, and a [[CD-ROM]] drive (recommended: [[Pentium II]], 128{{nbsp}}MB of RAM, 2{{nbsp}}GB of hard drive space, and CD-ROM drive).<ref name="SysReq">{{Cite web |title=System requirements for Microsoft Windows 2000 operating systems |url=http://support.microsoft.com/kb/304297 |url-status=live |archive-url=https://web.archive.org/web/20080416050811/http://support.microsoft.com/kb/304297 |archive-date=April 16, 2008 |access-date=May 23, 2008}}</ref> However, despite the official minimum processor requirements, it is still possible to install Windows 2000 on 4th-generation x86 CPUs such as the [[80486]].

'''Windows 2000 Embedded''' and '''Windows 2000 Professional Embedded'''/'''Windows 2000 Professional For Embedded Systems''' are versions of Windows 2000 Professional that was designed for [[Embedded system|embedded]] use, and targeted at [[ATM]]s, [[vending machine]]s and other large embedded devices. The FES versions function exactly the same as its retail counterpart, but is licensed for embedded use.<ref>https://download.microsoft.com/download/5/A/E/5AE5C363-E91C-401C-86A7-D817956DF629/WindowsEmbedded_Enterprise_Overview.pdf</ref>

'''Windows 2000 Server''' shares the same [[user interface]] with Windows 2000 Professional, but contains additional components for the computer to perform [[Server (computing)|server]] roles and run infrastructure and [[application software]]. A significant new component introduced in the server versions is [[Active Directory]], which is an enterprise-wide directory service based on [[Lightweight Directory Access Protocol|LDAP]] (Lightweight Directory Access Protocol). Additionally, Microsoft integrated [[Kerberos (protocol)|Kerberos]] network authentication, replacing the often-criticised [[NTLM]] (NT LAN Manager) authentication system used in previous versions. This also provided a purely [[Active Directory#Trust|transitive-trust]] relationship between Windows 2000 Server [[Windows Server domain|domains]] in a ''[[Active Directory#Forests, trees, and domains|forest]]'' (a collection of one or more Windows 2000 domains that share a common [[Active Directory#Objects|schema]], configuration, and [[Active Directory#Forests, trees, and domains|global catalog]], being linked with two-way [[Active Directory#Trust|transitive trusts]]). Furthermore, Windows 2000 introduced a [[Microsoft DNS|Domain Name Server]] which allows dynamic registration of [[Internet Protocol|IP]] addresses. Windows 2000 Server supports up to 4 processors and 4{{nbsp}}GB of RAM, with a minimum requirement of 128{{nbsp}}MB of RAM and 1{{nbsp}}GB hard disk space, however requirements may be higher depending on installed components.<ref name="SysReq" />

'''Windows 2000 Server Embedded''' and '''Windows 2000 Server For Embedded Systems''' are binary identical versions of Windows 2000 Server that was targeted at the embedded market. Both versions function exactly the same as its retail counterpart, but is licensed for embedded use.

{{Anchor|Windows 2000 Advanced Server|Windows 2K Advanced Server|2KAS}}
'''Windows 2000 Advanced Server''' is a variant of Windows 2000 Server operating system designed for medium-to-large businesses. It offers the ability to create [[Computer clustering|cluster]]s of servers, support for up to 8 CPUs, a main memory amount of up to 8{{nbsp}}GB on [[Physical Address Extension]] (PAE) systems and the ability to do 8-way [[Symmetric multiprocessing|SMP]]. It supports [[TCP/IP]] [[Network Load Balancing Services|load balancing]] and builds on [[Microsoft Cluster Server]] (MSCS) in Windows NT Enterprise Server 4.0, adding enhanced functionality for two-node clusters.<ref>''Microsoft''. Windows 2000 Resource Kit, Chap. 1, "Introducing Windows 2000 Deployment Planning."</ref> System requirements are similar to those of Windows 2000 Server,<ref name="SysReq" /> however they may need to be higher to scale to larger infrastructure.

{{Anchor|Windows 2000 Datacenter Server|Windows 2K Datacenter Server|2KDCS}}
'''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 (computing)|server]].<ref name="Datacenter">{{Cite web |date=February 28, 2007 |title=The Datacenter Program and Windows 2000 Datacenter Server Product |url=http://support.microsoft.com/kb/265173 |url-status=live |archive-url=https://web.archive.org/web/20111103061548/http://support.microsoft.com/kb/265173 |archive-date=November 3, 2011 |access-date=November 13, 2011 |website=Support.microsoft.com}}</ref> Like Advanced Server, it supports [[Cluster (computing)|clustering]], [[High-availability cluster|failover]] and [[Load balancing (computing)|load balancing]]. Its minimum [[system requirements]] are similar to those of Advanced Server,<ref name="SysReq" /> but it was designed to be capable of handing advanced, fault-tolerant and [[Scalability|scalable]] hardware—for instance computers with up to 32 CPUs and 32{{nbsp}}[[Gigabyte|GBs]] RAM, with rigorous system testing and qualification, hardware partitioning, coordinated maintenance and [[change control]].
