Applies To: Windows Server 2008
Active Directory Federation Services (AD FS) requires that the following applications be installed on a computer running Windows Server 2008 Standard or Windows Server 2008 Enterprise (only for servers hosting the AD FS Web Agent) so that the computer can host the Federation Service, Federation Service Proxy, or AD FS Web Agent role services of AD FS:
Internet Information Services (IIS)

When you add the Web Server (IIS) server role, these three applications are installed.
Membership in Administrators, or equivalent, on the local computer is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).
