Self-registration automatically publishes this site's interfaces as services and bindings in the UDDI Services registry and in Active Directory Domain Services (AD DS). Applications and services can then use this site to locate information about Web services that the site provides.  When you deploy multiple Web servers for a UDDI Services site, select self-registration for only one of the servers.
