Windows clients not updating dns

Hello, my office has a Windows 2003 server network set up using both DHCP and DNS on the DC.We have a problem where all XP machines are getting registered in DNS but our own developed equipment or network printers are not.get the windows copy if you don't have access to a Linux box which has it do; dig @external DNS-IP zone. onceyou have all the data you should be able to to see which NS are the problem, or at least where to look.I have 01 dhcp server on centos and windows dns server(active directory).If the Update Credentials works PREVIOUSLY then consider that this account may need an non-expiring password. DHCP server is NOT a member of the DNSUpdate Proxy group, should it be ?Our equipment (and also for example HP network printers) use option 81 in the DHCP protocol to specifically request the server to register both the DNS A and PTR records in DNS. I have checked the DHCP audit log but it shows no sign of authenticating or conneting problems. I'm NOT a system administrator, just a programmer ;-) Well, the problems we have began after a complete server hardware and software upgrade so it is certainly possible a mistake has been made...

The box is checked for "Use root hints if no forwarders are available".

Issue resolved, but I'm curious what value was preventing it from forwarding all day yesterday...

My understanding about /registerdns is that it is for clients to update their host records in DNS (A) that you host.

First this would tell me whether the DHCP server was ever SENDING the registration (and having it fail) or just messing up before that. My DHCP and DNS settings are: DHCP Settings: - Enable DNS Dynamic Updates according to the settings below - Always dynamically update DNS A and PTR records - Discard A and PTR records when lease is deleted - Dynamically update DNS A and PTR records for DHCP clients that do not request updates (for example, clients running Windows NT 4.0) - Lease duration: from 1 day to 4 days (depending what scope/vlan) DNS Settings: - Dynamic Updates: Nonsecure and secure.

- Scavenge set to 7 days I don't have the FQDN option 81 in the DHCP. to=296095728 =================================== When responding to posts, please "Reply to Group" via your newsreader so that others may learn and benefit from your issue, to respond directly to me remove the nospam. =================================== =================================== Use Outlook Express?
