Enabling and disabling dynamic updates

Enabling and disabling dynamic updates

Dynamic updates enable DNS clients to register and maintain their own address and pointer records. This is useful for computers dynamically configured through DHCP. By enabling dynamic updates, you make it easier for dynamically configured computers to locate one another on the network. When a zone is integrated with Active Directory, you have the option of requiring secure updates. With secure updates, you use ACLs to control which computers and users can dynamically update DNS.

You can enable and disable dynamic updates by following these steps:

1. In the DNS Manager console, press and hold or right-click the domain or subnet you want to update, and then tap or click Properties.

2. Use the following options in the Dynamic Updates list on the General tab to enable or disable dynamic updates:

? None Disable dynamic updates.

? Nonsecure And Secure Enable nonsecure and secure dynamic updates.

? Secure Only Enable dynamic updates with Active Directory security. This is available only with Active Directory integration.

3. Tap or click OK.

NOTE DNS integration settings must also be configured for DHCP. See “Integrating DHCP and DNS” in Chapter 8.
