# Configure IIS

#### **For Configuring IIS versions (before 6.0).**

* Select Start | Settings | Control Panel | Administrative Tools | Internet Information Services IIS Manager.
* Click on Web Services Extensions folder, you will see a list on the left hand side. When you initially install IIS, the services installed are in a highly secure and "locked" mode. By default, IIS serves only static content meaning features like ASP, ASP.NET, Server-Side and Front Page Server Extension do not work unless enabled. If you do not enable this functionality after installing IIS, IIS returns a 404 error. Refer the below image.
