Wiki

IIS stands for Internet Information Services (IIS, formerly Internet Information Server) which is an extensible web server created by Microsoft for use with Microsoft Windows.

Several versions of IIS have shipped over the years, the most recent being:

  • IIS 10.0 - shipped with Windows 10 Fall Creators Update and Windows Server 2016
  • IIS 8.5 - shipped with Windows 8.1/Windows Server 2012 R2
  • IIS 8.0 - shipped with Windows 8/Windows Server 2012
  • IIS 7.5 - shipped with Windows 7/Windows Server 2008 R2
  • IIS 7.0 - shipped with Windows Vista/Windows Server 2008
  • IIS 6.0 - shipped with Windows 2003
  • IIS 5.1 - shipped with Windows XP Professional
  • IIS 5.0 - shipped with Windows 2000
  • IIS 4.0 - shipped with Windows NT Server/Workstation 4.0

Tag usage

The tag can be used for programming related problems when configuring IIS server for web development purposes. The tag can also be used for programming problems in implementing IIS services using IIS server.

Please note that https://serverfault.com/ is another StackExchange website, which can be used for more specific server installation and configuration related problems.

Important: Please ensure that you mention which version of IIS you're working with when asking a question. For example, there is a world of difference between IIS6 and IIS7+ and these products are very different, operationally and architecturally.
