How to Enable DNS Dynamic Updates to a DNS Server

Windows 2000 DHCP and DNS servers now support dynamic updates to a DNS server. Windows 2000 clients can dynamically update their forward lookup records themselves with the DNS server after the clients obtain a new IP address from a DHCP server.

In Windows 2000 DHCP server, you can dynamically update the DNS records for pre-Windows 2000 clients that cannot do it for themselves. This feature currently works only with the Windows 2000 DHCP and DNS servers.

To enable a DHCP server to dynamically update the DNS records of its clients:

1. Select the scope or DHCP server on which you want to permit dynamic DNS updates.
2. On the Action menu, click Properties, and then click the DNS tab.
3. Click to select the Automatically Update DHCP Client Information In DNS check box.
4. To update a client’s DNS records based on the type of DHCP request that the client makes and only when it is requested, click Update DNS Only If DHCP Client Requests.
5. To always update a client’s forward and reverse lookup records, click Always Update DNS.
6. Click to select the Discard Forward Lookups When Leases Expire check box to have the DHCP server delete the Host resource record for a client when its DHCP lease expires and is not renewed.
7. Click to select the Enable Updates For DNS Clients That Do Not Support Dynamic Updates check box to enable the DHCP server to update the forward and reverse lookup records for clients that cannot update their own forward lookup records. If you do not select this check box, the DHCP server does not automatically update the DNS records of non-Windows 2000 clients.
