Server operating system and infrastructure: The Windows NT Server network operating system version 4.0 is the server operating system which combines support for the Internet along with a file server, an application server, and a communications server. Integrated Internet support includes native Internet protocols (e.g. DHCP), high performance Web server, Web site authoring and management system, search server, directory server, and support for secure communications over the public network. This combination of services supports the expanded role of the Internet as it handles static pages as well as presenting applications as Web pages. Many applications already exist for this operating system platform and it continues to be an easy target environment when developing client/server applications.

Windows NT Server is also very scaleable making it a secure foundation taking companies well into the next century. New extensions like clustering support and 64-bit addressing for very large memory (VLM) support will help to address the high performance needs of more demanding computing requirements. As IT organizations are being asked to do more with less, Windows NT Server and its integrated services have been designed to be unmatched in ease of administration.
