NIC 2枚ざしの DNS 登録

登録に使わない NIC のプロパティで DNS に登録しないようにしておいても自動的に登録されてしまう問題に関して、Microsoft のサイトによると、DNS サーバ0のプロパティの詳細でラウンドロビンをチェックはずしとかなきゃいけないらしい。


To resolve this issue: 1.Disable registration on the outside network adapter on the multihomed domain controller. To do so:a.Click Start, click Settings, and then click Network and Dial-Up Connections.
b.Right-click the outside local area network (LAN) connection, and then click Properties.
c.Click TCP/IP, and then click Properties.
d.Click Advanced, and then click to clear the Register DNS for this connection check box.

2.Disable the round robin functionality on the DNS server. To do so:a.Click Start, click Settings, click Administrative Tools, and then click DNS.
b.Open the properties for the DNS server’s name.
c.Click the Advanced tab, and then click to clear the Enable round robin check box.

3.Remove the existing entries in DNS. To do so:a.Browse to the following location:
Under DNSDNS ServernameForward Lookup ZonesDomain Name

b.Remove Host (A) record entries that refer to the domain controller’s computer name for the outside network adapter IP addresses.
c.Remove Host (A) record entries for the same name as the parent folder for the network adapter IP addresses.

4.Start the DNS Management Console, right-click the server name, and then click Properties.
5.Click the Interfaces tab, and then remove the external IP address so that DNS does not listen on it.
6.Open a command prompt, type ipconfig /flushdns, press ENTER, type ipconfig /registerdns, and then press ENTER.
7.Change the binding order of your network adapters so that the Internal adapter is the first bound adapter. To do this, follow these steps:a.Click Start, click Settings, and then click Network and Dial-Up Connections.
b.On the Advanced menu, click Advanced.
c.Verify that the internal network adapter is listed first in the Connections box
