Update dns records server

The article discusses how to disable DNS updates in Windows. By default, client computers have DNS updates enabled. By default, this behavior is enabled for Windows DNS clients. Depending on the configuration and services that are running on a particular computer, different components perform DNS updates.

There's no centralized way, such as a tool or registry keys, to manage the DNS update behavior of all components. This article describes each component and how to modify that particular component's behavior. The article also discusses how to disable DNS updates in Windows. After you change one of these components by modifying the registry keys that are listed in this article, you must stop and restart the affected services.

Sometimes, you must restart the computer. These instances are noted. 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, see How to back up and restore the registry in Windows.

This section describes how to enable and disable the following lookup registrations:. To disable both forward A resource record and reverse PTR resource record registrations that are performed for all adapters by the DHCP Client service, use the following registry subkey:. If the check box was checked before the policy was enabled, it will still be checked after the policy is enabled. The registry setting made by the policy is a global setting that affects all interfaces, not an adapter-specific setting.

This key disables DNS update registration for all adapters on this computer. With DNS update, DNS client computers automatically register and update their resource records whenever address changes occur. To disable DNS update for a particular adapter, add the DisableDynamicUpdate value to an interface name registry subkey and set its value to 1. To disable DNS updates on all adapters in a computer, add the DisableDynamicUpdate value to the following subkey, and then set its value to When this registry value is set to 1, the Register this connection's addresses in DNS check box will not reflect the changes made to this registry key.

If the check box was selected before the registry change, it will stay selected after this registry change. This registry setting is not an adapter-specific setting, but a global setting that affects all interfaces. This global setting is not revealed in the user interface. Windows doesn't add this entry to the registry.

You can add it by editing the registry or by using a program that edits the registry. When you want forward lookup A resource record registrations but not reverse lookups PTR resource record registrations, use the following registry subkey to disable registrations of PTR resource records:.

PTR resource records associate an IP address with a computer name. This entry is designed for enterprises where the primary DNS server that is authoritative for the reverse lookup zone can't, or is configured not to, perform DNS updates. It reduces unnecessary network traffic and prevents event log errors that record unsuccessful tries to register PTR resource records. Windows does not add this entry to the registry. Each computer has a primary DNS suffix.

Additionally, each adapter can also have a separate DNS suffix that is configured for itself. This disables DNS update registration on this adapter.
