In 1999, Microsoft changed the operating system’s name from Windows NT to
Windows 2000, which was available in four packages: Windows 2000 Professional,
Windows 2000 Server, Windows 2000 Advanced Server, and Windows 2000
Datacenter Server. The Datacenter Server was a new product designed for large data
warehouses and other data-intensive business applications, and supported up to 64GB
of physical memory. Likewise, Windows Server 2003 was also released with these
same four packages plus a Web edition.
