4.4.2 Deconfigure DNS Registration for Public Network Adapter
To prevent Windows Server from potentially registering the wrong IP addresses for the node in DNS after a server restart, you must deconfigure the "Register this connection's addresses in DNS" option for the public network adapters.
Due to a change in functionality in the Windows Server 2008 operating system, the DNS client service registers all of the network connections of a computer in DNS. In earlier versions of Windows Server, the DNS client service registered only the primary, or first, network adapter IP address in DNS.
