2K Clients not updating DNS dynamically

By dgemcse ·
2K server, with DHCP and DNS on same machine.

Defualt settings on 2K client should enable DHCP to update the DNS with FQDN. I have looked all over MS and elsewhere. For some weird reason, some of the clients update DNS and some don't. ALL clients are on same net, no FW or routers seperating them.
Clients are using defualt settings of "append primary and connection specific" and "register this connections address in DNS". Server is set to accept dynamic, and like I said, some clients update, while some don't.
Only workaround I have found is enabling "use this connections DNS suffic in registraton", BUT not all clients have this set.
Any suggestions?
As I mentioned, ALL clients recive DHCP without issue, and SOME register with just NB name, and some register FQDN...I have tested this with adding appending domain name to NB, but that is not practical.
I want to be able to have ALL clients receive DHCP address and domain info, then regiter this with DNS...currently using what I have working in DNS, and WINS (long story, but I can't fully move to DNS until i can figure out why this happens). Is there no way this can happen dynamically.?.?..(I know the answer to that one!)

Thanks!!

Have you ran the command ipconfig /flushdns on the DNS server and clients?

Are the clients all Windows 2000?

Hmmm, a windows feature not working as advertised. Well, I guess it keeps us all employed :)

Have you tried getting the DHCP server to do the DNS updates itself. Open the DHCP console and open Properties on the server object. On the DNS tab you can enable the DHCP server to always make the updates. Good ole brute force solution. I haven't tried this myself mind you.

Have you set up ALL the different IP scopes with the relevant DHCP, DNS and WINS settings.

Is the DNS suffix specified in the domain/ou group policy? You may have to delete and recreate computer accounts (in the right ou's before they are created to ensure properties are set right)

Because WINS is a backup protocol is it possible that some computers have registered through DNS and some through WINS thus creating different records. Consider checking the time out values, and the server availability. (network monitor?)Also, check that the WINS server has been set up to properly register with DNS.

From the pocket guide.... Integrating WINS with DNS

Still looking...
BTW, the DNS server (which is NOT AD) shows no abnormal EV activity...just happy writing zone files....maybe I should have included that with the original request.
All types of clients, even Mac's...some register, some don't...DHCP is set to update ALL....
Also, not a TLD, just internal domain.
All the info I have seen (and always used) as far as defualt for this to happen always just "worked"...what could play a part in having ANY client talk to a DHCP srver, register, but NOT register with DNS?
I'm about to the point of scrapping the DNS server and just rebulilding it..this is definatle not normal!!!

Thanks!!!
