Can static IP addresses update DNS dynamically?

I'm in the process of testing my W2K migration and I'm having some issues
with DNS dynamic updates. I understand that DHCP clients can dynamically
update DNS, but what about clients with static IPs? Will they updated
dynamically or do I have to manually input them in to DNS?

I have a workstation with a static IP and it's not updating DNS. Just
wondering what the process is, if any. Incidentally, I have tried updating
it with the IPCONFIG /REGISTERDNS command with the DHCP client service
turned ON and OFF. No dynamic update either way.

Any guidance would be most appreciated. Thanks in advance.

Yes.
Check the dhcp client service is started on the client (even if it is
static.) It is code in the dchp client service that does the dyamic update.

Actually it's Windows 2000 class machines that do dynamic updates
to DNS -- the service responsible is the "DHCP Client" even if you
aren't 'using' DHCP actively. That might have confused the issue.

Leave the DHCP client running, make sure the NIC/IP properties/Advanced/
DNS setting for "register this interface" is checked (still).

Other replies covered all the important points, save one.
Your zone must allow DDNS updates.

I thought that, too. But I tested updates with workstations who HAD the
'disabledynamicupdate' key and with those who did NOT have the
'disabledynamicupdate' key. Those workstation who did not have the key
updated instantly, those who did have it could not update. So I don't think
it was corrupt.

I understand(and I could be wrong) that this key has to be manually entered
in to the registry and that it is not loaded by default. We are with the DOD
and the security scripts we have to run are pretty stringent, so..... it's
possible the script added the key. Just a theory...

Hmm. DOD Scripts?

Maybe, SP4 installed it, err, what SP is this machine on?.
