Definition of Internet Information Services (IIS) in The Network Encyclopedia.

What is IIS (Internet Information Services)?

The service integrated into the Microsoft Windows 2000 Server operating system platform that provides support for application-layer Internet protocols. In the earlier Windows NT Server platform, IIS stood for “Internet Information Server” and was an optional component of Windows NT Server.

Internet Information Services (IIS) is also the foundational component for a wide variety of Microsoft Internet and intranet solution platforms, including Microsoft Site Server, Microsoft Commercial Internet System (MCIS), and other Microsoft BackOffice products.

IIS has evolved since it was first released for Windows NT 3.51 into its current version 5.0 for the Windows 2000 platform. The highest version available for the Windows NT platform is version 4.01, which was included as part of the Windows NT Option Pack. Both IIS versions 4.01 and 5.0 support the following features:

  • Fully integrated with Windows NT security and the version of NTFS used in Windows NT
  • Full support for version 1.1 of Hypertext Transfer Protocol (HTTP)
  • Support for File Transfer Protocol (FTP)
  • Limited support for Simple Mail Transfer Protocol (SMTP)
  • Support for Network News Transfer Protocol (NNTP)
  • Support for advanced security using the Secure Sockets Layer (SSL) and related protocols
  • Provides a platform for deploying scalable Web server applications using Active Server Pages (ASP); Internet Server API (ISAPI); Common Gateway Interface (CGI); Microsoft Visual Basic, Scripting Edition (VBScript); JScript; and other installable scripting languages such as Perl
  • Allows Web applications to be run as isolated processes in separate memory spaces to prevent one application crash from affecting other applications
  • Integrates with Microsoft Transaction Server (MTS) and Microsoft Message Queue (MSMQ) Server for deploying transaction-based Web applications
  • Can be managed using the Microsoft Management Console (MMC), through a standard Web browser such as Microsoft Internet Explorer, or by running administrative scripts using the Windows Scripting Host (WSH)
  • Includes domain blocking for allowing/granting access on the basis of IP address or domain
  • Allows IIS activity to be logged in various formats including IIS, World Wide Web Consortium (W3C), National Computer Security Association (NCSA), and open database connectivity (ODBC) logging
  • Allows Web site operators to be assigned for limited administration of each Web site
  • Bandwidth throttling to prevent one Web site from monopolizing a server’s available bandwidth

IIS 4 offers only Microsoft Personal Web Server (PWS) for Windows NT Workstation, Windows 95, or Windows 98.

The latest version of IIS is IIS 10 and is included in Windows Server 2016. You can buy it right now on Amazon store clicking here.
