DHCP and Dynamic DNs

[mmorgensen]

Hello,

I am trying to get this to work in my test lab before i deploy it to the company at large. We have a windows 2003 domain. DNS is installed on the DC's. DHCP is installed on a member server in the domain. DHCP is configured to dynamicly update the dns on behalf of the clients (both forward and reverse records).

Currently the testing is working 100% with the dhcp client is a member of the domain. However, when the dhcp server tries to register a client who is NOT a member of the domain it receives an error when reg. the forward lookup...the reverse lookup works.

The dhcp server shows a different suffix for each type of computer

name1.labone.siteone.local (<= member of the domain)
name2. (<= not in the domain)

I assume the lack of "labone.siteone.local" is the reason the registration fails.

From my DHCP logs:
DNS Update Successful,10.0.34.222,name1.labone.siteone.local

DNS Update Failed,10.0.34.221,name2.,2,
^^ see the lack of a domain name attached to the request.


BTW: My DHCP servers are set to hand out the DNS domain name of "labone.siteone.local"


any ideas?

Is your DNS AD Integrated? one of the benefits of DDNS is it gives you the added security of restricting DDNS registrations to computers that are members of the domain.

I hope you find this post helpful. Please let me know if it was.

Yes we do have DNS integrated with AD. But I need Linux clients, and non domain clients, to be able to register then names in DNS.

Thanks!

Does your DNS zone only allow secure dynamic updates?

I tried it both ways, secure and not secure.

no luck.
