Windows 2000 Professional has a feature called Dynamic DNS (DDNS) that enables host records to be updated automatically in a Windows 2000 DNS server when the client address changes. This enables host records to remain accurate even when clients receive their address assignments through DHCP, for example.
A Windows 2000 Professional client can request an update to its host (A) record in the DNS server when its IP address or host name changes. A Windows 2000 DHCP server can also request an update to the associated pointer (PTR) record on behalf of its DHCP clients.
To configure a client for DDNS, follow these steps:
- Open the Properties sheet for the network connection through the Network And Dial-Up Connections folder.
- Double-click TCP/IP.
- Go to Advanced | DNS.
- Select the Register This Connection’s Addresses In DNS option to enable DDNS for the client. Note: The Use This Connection’s DNS Suffix In DNS Registration option, if selected, registers the client using the first part of the computer name specified in the System properties along with the DNS suffix specified by the DNS Suffix For This Connection option.
