Technically that will work, however, dynamic DNS does not offer the same information as WINS does currently in a Samba implementation. Since Samba is not emulating an AD domain controller, but an NT4 domain controller, the workstations are expecting certain information to be returned about machines (the various flags after the names you see in WINS) as far as their capabilities are concerned. This is offered in WINS (also in DNS, through the use of SRV records, but Samba does not generate these currently and I don't know how the workstations would interact, finding the entries it would expect an AD controller to use in DNS and then finding an NT4 domain controller there). If you're all on the same subnet, this is not a problem because it can find the same information through broadcast resolution, but who's all on the same subnet these days? :) The Samba3 HOWTO covers this very well under name resolution.

Could we maybe get round using WINS by using Dynamic DNS so the Netbios name always matches the IP address? Then change "name resolve order" so it used DNS before WINS. We use Bind 9 and ISC DHCP v3 already so it is possible to setup. Or am I talking rubbish?

[Samba] Re: WINS not updating after swapping network connections
I had the exact same problem when I changed from dynamic IP to Static on the server itself. It added the new IP address AFTER the old one in wins.dat, and only reported the first back to the clients. Try shutting down Samba, deleting wins.dat (May be in either /var/cache/samba/ or /var/lib/samba/ ) then starting Samba up again. Your WINS file will be rebuilt as the clients re-register their addresses. How to actually get it to change on the fly, however, is anybody's guess, as it will re-write the file as-is if you delete / change it while SAMBA is running. It was suggested that it may be a corrupted file, so just deleting it and letting it be re-built may fix the problem, too.
