You can install Internet Information Services (IIS) 6.0 by using Add/Remove Windows Components from Add or Remove Programs in Control Panel.
As a security best practice, log on to your computer using an account that is not in the Administrators group, and then use the Run as command to run IIS Manager as an administrator. At the command prompt, type runas /user:administrative_accountname mmc %systemroot%\system32\inetsrv\iis.msc.
In Control Panel, double-click Add or Remove Programs.
Click Add/Remove Windows Components.
In the Components list box, click Application Server, and then click Details.
In the Subcomponents of Application Server box, click Internet Information Services (IIS).
Click OK to start the installation of IIS 6.0.
