Dynamic dns records not updating


23-Jul-2015 01:03

That doesn't exactly seem to be the case from your experience, but might be close.... Massimo, are you able to pull a wireshark trace and check the DHCPREQUEST Packet?

There should be a flag set to "1" if the client is supposed to update both the A record and PTR record.

So I have this weird issue on my DHCP server where random computers don't update the DNS records and I have to manually run ipconfig /registerdns on the client computer to force the update.

To make myself understood I'll give you this example: A computer connects to VPN, it gets an IP from another subnet, the DNS is updated accordingly.

And make sure the DNS dynamic update credentials are correct and appropriate permissions are applied for this to work As I said in the question, configuring the DHCP server is not an option. It won't register DNS records for its clients, period.

When a new client gets an IP address, DHCP doesn't update DNS with the record. The DHCP and DNS are on the same box (which is also the primary DC).

I have checked the event viewer logs for the DHCP and DNS server but nothing is present?

A flag of "0" means the client updates the A record and requests that the server update the PTR record on its behalf. Also in the DHCP scope make sure == Click the DNS tab, click Properties, and then click to select the Dynamically update DNS A and PTR records only if requested by the DHCP clients check box == is set.

This would mean when the default flag of "0" comes in the server will then try to register the PTR record with the DNS server(s) it is configured to update.
