The Host's "A" Record Is Registered in DNS After You Choose Not to Register the Connection's Address
For example, this behavior may occur if you have the following configuration:
- The DNS service is installed on the server.
- The DNS server zone is example.com, where the example.com zone can be updated dynamically.
- The server host name is Server1.example.com, where Server1 has two network adapters that have IP addresses of 10.1.1.1 and 10.2.2.2.
- The DNS service is installed on the server whose configuration you are trying to change.
- The DNS zone that matches the primary DNS suffix of the server is enabled to update dynamically.
Method 1Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
Configure the DNS service to publish specific IP addresses to the DNS zone. To do so, make the following registry modification:
Data type: REG_SZ
Range: IP address [IP address]
Default value: blank
This entry is for computers that have multiple IP addresses, only a subset of which you want to publish. Typically, this prevents the DNS server from returning a private network address in response to a query when the computer has a corporate network address.
DNS reads its registry entries only when it starts. You can change entries while the DNS server is running by using the DNS console. If you change entries by editing the registry, the changes are not effective until you restart the DNS server.
The DNS server does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
Method 2Remove the interface from the list of interfaces that the DNS server listens on. To do so, follow these steps:
- Start the DNS Management Microsoft Management Console (MMC).
- Right-click the DNS server, and then click Properties.
- Click the Interfaces tab.
- Under Listen on, click to select the Only the following IP addresses check box.
- Type the IP addresses that you want the server to listen on. Include only the IP addresses of the interfaces for which you want a host A record registered in DNS.
- Click OK, and then quit the DNS Management MMC.
Data type: REG_DWORD
Range: 0 - 1
Default value: 0
If you remove an IP address from the list of the DNS server's listening interfaces, the server no longer accepts DNS requests that are sent to that IP address. This option is sometimes used in situations where the DNS server is also a domain controller and has an interface that is connected to a disjointed network. For this configuration, make sure that Active Directory client computers do not direct any queries to an interface that they cannot reach.
