The DomainDNSRegistrationEnabled parameter specifies whether the IP addresses for this connection are registered in DNS under the domain name of this connection, in addition to registering under the computer's full DNS name. The domain name of this connection is either set via the method SetDNSDomain() or assigned by DHCP. The registered name is the host name of the computer with the domain name appended. This parameter has meaning only when FullDNSRegistrationEnabled is enabled. Default: FALSE. Windows 2000 only.
