How does DDNS replace WINS in Windows 2000 and later?

DDNS replaces WINS by allowing DNS clients to update information in the DNS database files. IP Addresses and DNS records stay in synch so that you can use DNS and DHCP together seamlessly. WINS listens to NBT broadcasts and can not update IP Address information if the DHCP lease expires since the NBT broadcasts registers the machines IP Address with the WINS Server at boot up. NetBIOS is not routable which further complicates things. WINS servers use NetBIOS names whereas DNS relies on hostnames.

Under what circumstances would we still use WINS?

WINS should be used whenever your network contains pre-Windows 2000 operating systems or you run NetBIOS dependent services on your network. Pre-Windows 2000 operating systems are dependent on NetBIOS for important domain related activities such as log on authentication and service location. WINS should also be considered as a means to improve resolution performance. You must be very cautious when deploying WINS Servers. Too many can create more problems than it is worth. WINS can help increase resolution speed because it is higher on the list for NetBIOS resolution. The resolution sequence is as follows:

NetBIOS Remote Name Cache

WINS

Broadcast

LMHOSTS

HOSTS

DNS

As you can see, DNS lookups are performed last, after other methods are employed.
