ASP.NET Impersonation and Forms Authentication missing

Question

_{Thursday, June 3, 2010 2:42 PM}

On windoes 7, the default authentication for any site on IIS are:

Anonymous Authentication
ASP.NET Impersonation
Forms Authentication

Then I went to Control Panel -> Programs and Features -> Windows Features -> IIS -> WWW Service -> Security and made some changes.

Then Open IIS manager again,  ASP.NET Impersonation and Forms Authentication are missed for any site. For any site, the future view should have sections: ASP.NET and Management before. But now only IIS and Management section. ASP.NET section disappear too!

How to fix this problem?

In the same Windows Features dialog, make sure that the features ASP.NET and .NET Extensibiilty are installed.
