Turn off Federation Service

This policy setting prevents a Federation Service in Active Directory Federation Services (AD FS) from being installed or run.

If you enable this policy setting, installation of a Federation Service fails. If a Federation Service has already been installed, all requests made to it fail.

If you disable or do not configure this policy setting, installation of a Federation Service is allowed and any installed Federation Service functions normally.

Note: A Federation Service may be installed only on Windows Server 2008 Enterprise Edition or Windows Server 2008 Datacenter Edition.

Supported on: At least Windows Vista
