# Overview

Internet Information Services (IIS) is a Web Server role developed by Microsoft and included with all Microsoft's operating systems. By default the IIS is typically not turned on when the operating system is installed. In order to host the i2b2 Web Client the IIS needs to be turned on.

The following steps will outline the process of Installing IIS7.0 on Windows Server 2008. If you are using a different version of Windows Server or IIS it is recommended you follow the instructions defined by Microsoft. You can find out more information about IIS by visiting the following website: [http://www.iis.net/](http://www.iis.net/)

2. In the **Server Manager** window, select **Roles** from the panel on the left. The Roles Summary view will display on the right.
