Answer: 
Explanation:
Active Directory Federated Services (AD FS) is required to support single sign-on.
On a Windows Server 2008 computer AD FS can be installed as a separate installation package known as AD FS 2.0. The .NET Framework 3.5 with Service Pack 1 is a prerequisite for AD FS 2.0 software and is not automatically be installed by the AD FS 2.0Setup Wizard. We must therefore install the .NET Framework 3.5 with Service Pack 1 first.
Once .NET Framework 3.5 with Service Pack 1 is installed, we can run the AD FS 2.0 installation package.
Once AD FS 2.0 is installed, we must install the AD FS hotfixes. The hotfixes are included in Update Rollup 3 for AD FS 2.0.
