When you duplicate a version 1 or version 2 certificate template, you can make the duplicate a version 2 or version 3 template in order to configure the advanced options available with the later versions. However, version 3 certificate templates can only be issued by Windows Server 2008–based enterprise CAs and used by clients on computers running Windows Server 2008 or Windows Vista®. For more information, see Certificate Template Versions.

For information about configuration options for certificate templates, see Configuring a Certificate Template.
