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.
- Start the Windows Server Manager application.
- Select View Network Connections.
- Right-click the network adapter that provides the Public network interface and select Properties.
- Select the Networking tab, and then select Internet Protocol Version 4 (TCP/IPv4).
Note:If you configure this setting in IPv4, then Windows automatically configures the same setting for IPv6
- Click Properties.
- On the General tab, click Advanced.
- Select the DNS tab.
- Deselect Register this connection's addresses in DNS.
