29. A long form of an object's name in Active Directory that explicitly indicates the object name - plus the names of its containers and domains. It includes a DC (domain component) - OU (organizational unit) - and CN (common name).






30. On a SIP network - a server that accepts requests for location information from user agents - then queries the nearest registrar server on behalf of those user agents. If the recipient user agent is in the SIP proxy server's domain - then that server






31. A group of users - servers - and other resources that share account and security policies through a Windows Server 2003 or Server 2008 NOS.
