Internet Information Services

Summary
Internet Information Services (IIS) is an extensible web server created by Microsoft for use with the Windows NT family. IIS supports HTTP, HTTP/2, HTTPS, , FTPS, SMTP and NNTP. It has been an integral part of the Windows NT family since Windows NT 4.0, though it may be absent from some editions (e.g. Windows XP Home edition), and is not active by default. The first Microsoft web server was a research project at the European Microsoft Windows NT Academic Centre (EMWAC), part of the University of Edinburgh in Scotland, and was distributed as freeware. However, since the EMWAC server was unable to handle the volume of traffic going to Microsoft.com, Microsoft was forced to develop its own web server, IIS. Almost every version of IIS was released either alongside or with a version of Microsoft Windows: IIS 1.0 was initially released as a free add-on for Windows NT 3.51. IIS 2.0 was included with Windows NT 4.0. IIS 3.0, which was included with Service Pack 2 of Windows NT 4.0, introduced the Active Server Pages dynamic scripting environment. IIS 4.0 was released as part of the "Option Pack" for Windows NT 4.0. It introduced the new MMC-based administration application and also was the first version where multiple instances of web and FTP servers can run, differentiating them by port number and/or hostname. It was also the first version to run application pools. IIS 5.0 shipped with Windows 2000 and introduced additional authentication methods, support for the WebDAV protocol, and enhancements to ASP. IIS 5.0 also dropped support for the Gopher protocol. IIS 5.0 added HTTP.SYS. IIS 5.1 was shipped with Windows XP Professional and was nearly identical to IIS 5.0 on Windows 2000. IIS 6.0 included with Windows Server 2003 and Windows XP Professional x64 Edition, added support for IPv6 and included a new worker process model that increased security as well as reliability. HTTP.sys was introduced in IIS 6.0 as an HTTP-specific protocol listener for HTTP requests.
