This is the default configuration for DHCP servers running Windows Server 2003 and DHCP clients running Windows 2000, Windows XP, or a Windows Server 2003 operating system. In this mode, the DHCP client can request the way in which the DHCP server performs updates of its host (A) and pointer (PTR) resource records. If possible, the DHCP server accommodates the client request for handling updates to its name and IP address information in DNS.
