Dynamic Update and Secure Dynamic Update Considerations

Clients and servers that are running versions of Windows earlier than Windows 2000 do not support dynamic update. However, Windows 2000 DHCP servers can perform dynamic updates on behalf of clients that do not support the FQDN option. If a Windows 2000 DHCP server must perform a secure dynamic update on behalf of clients that are running a version of Windows earlier than Windows 2000, you can place that DHCP server in a special security group called DNS Update Proxy. Objects created by the DNS Update Proxy group have no security, so they can be updated by any computer on the network.

For more information about these issues, see "Dynamic Update and Secure Dynamic Update" earlier in this chapter.
