To install IIS, first obtain your Windows installation media. Note that IIS version 6 or higher is required. 


Once you have your Windows installation media, go to Start → Control Panel → Add / Remove Programs. Then select 'Add / Remove Windows Components.' The exact location of the IIS feature may vary depending on your operating system. If you have any doubt, please contact your system administrator or [email protected]


In addition to the core WWW server component, you must install the following IIS components that are not enabled by default: 

  • ISAPI Extensions
  • IIS Metabase and IIS 6 configuration compatibility


This component is not required, but highly recommended: 

  • Dynamic Content Compression


This feature is used in lieu of the GZIP_ENCODING=Yes setting used on Lighttpd. The GZIP_ENCODING setting has no effect when running under IIS – content compression is enabled or disabled through the Dynamic Content Compression feature of IIS,
