compdigit44 used Ask the Experts™
We are having DHCP / DNS update issues and all recommned setting from Microsoft have not helped. On our DNS servers which are also DC's the ListenAddresses is set to a Null Value? Is this the default and if so should I try to change it as recommended in the following article?

I have this for all my DC's as well, the listenaddress value is null. I have no problem with dynamic DNS registration.

I came across this same article myself when investigating a dynamic DNS registration problem with DHCP, but it seemed irrelevant so I ignored it.

As an alternative possible solution, I would recommend looking to your DHCP logs. If you do not have logging enabled then enable it. What I found was that dynamic DNS registrations were failing because somebody set up a DHCP scope for BYOD devices that had a multitude of DNS suffixes for which I had no DNS zone. So thousands of BYOD devices were trying to register for a DNS zone that did not exist (bobs-mpb.home.local, janes-ipad.local, etc.). This led to the DNS update queue maxing out on the DHCP server (I think the default queue size is 2000) which led to DNS registrations failing intermittently for legitimate devices.

The fix is simple (for my scenario), disable dynamic DNS registrations for scopes that these people had setup for dynamic registration via the scope properties (DNS tab).

The particular errors I was seeing in DHCP were of course ID 31 but also ID 34 "DNS update requests queue limit exceeded". I think DNS gets blamed a lot, but as long as you have your DHCP service account in the DnsUpdateProxy group and your scopes are correctly configured you should be fine.

Interestingly in server 2016 you can now apply DNS suffix rules around DHCP dynamic DNS updates which is super cool.


thank you very much I do have DHCP logging enabled but it just says DNS update filed with the host name and not much more valuable information.
Does the DNS suffixes for the fails match your internal DNS zones?
Have you configured the DHCP service account, an have you configured all of your DHCP servers to use the same DHCP service account?
Is your DHCP service account a member of the DnsUpdateProxy group? (see here).


Yes everything is configured corrected and did open a case with MS support who confirmed our setup is correct. We are now looking at more of a network connection issue
