You can use the following registry key to modify the number of IP addresses that are dynamically registered for an adapter that is configured with more than one IP address, or is logically multihomed:. This setting determines the maximum number of IP addresses that can be registered in DNS for this adapter.
By default, non-secure DNS registrations are tried. You can use the following registry subkey to modify this behavior:.
This determines whether the DNS client uses secure dynamic update or standard dynamic update. Windows supports both dynamic updates and secure dynamic updates. With secure dynamic updates, the authoritative name server accepts updates only from authorized clients and servers.
This prevents the DNS client from overwriting an existing resource record when it discovers an address conflict during dynamic update. However, you can use this entry to direct DNS back out of the registration process. An error in Event Viewer isn't logged. This entry is designed for zones that don't use secure dynamic update.
It prevents unauthorized users from changing the IP address registration of a client computer. The DNS Server service registers host name A resource records for all the adapters that the service is listening on if the service is authoritative SOA for a particular name.
When a server that is running the DNS Server service has multiple adapters, unwanted addresses can be automatically published.
Common scenarios include disconnected or unused network adapters that publish AutoNet addresses and private or perimeter network DMZ interfaces that publish unreachable addresses. If the Network Load Balancing service is installed on a DNS server, both the virtual network adapter address and the dedicated network adapter address will be registered by the DNS Server service.
In Server properties , click the Adapters tab. If the list of IP addresses that the DNS server listens to and serves is different from the list of IP addresses that is published or that is registered by the DNS Server service, use the following registry subkey:. This value specifies the IP addresses that you want to publish for the computer.
The DNS server creates A resource records only for the addresses in this list. If this entry doesn't appear in the registry, or if its value is blank, the DNS server creates an A resource record for each of the computer's IP addresses. This entry is designed for computers that have multiple IP addresses. With this entry, you can publish only a subset of the available addresses. Typically, this entry is used to prevent 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. If you change entries by editing the registry, the changes aren't effective until you restart the DNS server. The DNS server doesn't add this entry to the registry. This log file lists records that are required to be registered for this domain controller. You may download and follow the instructions below to setup the client. If you have an older version of the client, we suggest that you download and use the latest version 5.

This default configuration causes the client to request that the client register the A resource record and the server register the PTR resource record. If the DHCP server is configured to register DNS records according to the client's request, the client registers the following records:.
To configure the client to make no requests for DNS registration, click to clear the Register this connection's address in DNS check box. A client is multihomed if it has more than one adapter and an associated IP address. If you do not want the client to register all its IP addresses, you can configure it not to register one or more IP addresses in the network connection properties.
You can also configure the computer to register its domain name in DNS. For example, if you have a client that is connected to two different networks, you can configure the client to have a different domain name on each network. Click to select the Enable DNS dynamic updates according to the settings below check box to enable DNS dynamic update for clients that support dynamic update.
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: How to back up and restore the registry in Windows.
By default, dynamic updates are configured on Windows Server-based clients. To disable dynamic updates for all network interfaces, follow these steps:.

Please rate your experience Yes No. Any additional feedback? Note The update process for Windows-based computers that use DHCP to obtain their IP address is different from the process that is described in this section.
The update process that is described in this section assumes that Windows installation defaults are in effect. Besides the full computer name, or the primary name, of the computer, you can configure additional connection-specific DNS names and optionally register or update them in DNS. Note Names are not removed from DNS zones if they become inactive or if they are not updated within the update interval of twenty-four hours. To avoid this issue, deploy DHCP servers and domain controllers on separate computers, or configure the DHCP server to use a dedicated user account for dynamic updates.
Note The secure dynamic update functionality is supported only for Active Directory-integrated zones. Note If you are using multiple DHCP servers for fault tolerance and secure dynamic updates, add each server to the DnsUpdateProxy global security group. Important This section, method, or task contains steps that tell you how to modify the registry. Note interface is the device ID of the network adapter for the interface that you want to disable dynamic update for.
