Changed AD IP addr resulted in DNS errors

I have done this in the past, but it appears this time when I changed the IP address of one of my Active Directory DC servers, it has caused an issue with my DNS.

The original IP address of the server was 192.168.1.5 and I changed it to 192.168.1.21

As a result when I run DCDiag /TEST:Dns, I get the error messages below.

What do I need to do to fix this?

Thank you,
Jeff

Output of DCDiag follows:

Can you please make sure that the old IP-address is not within DNS anymore.
You can do this by checking domain kwik.dom and verify that the domain controller computername has the correct IP-address.
If you have reverse zones also check these. Delete the records with the wrong IP-address.
After that start a command prompt (with Run as administrator) and execute: ipconfig /registerdns
This will register the A and PTR records for the domain controller.

Did you already restart the domain controller after changing the IP-address.
If you can't restart then try to restart the "DNS Server" service.
Also restart the Netlogon service.
This will register the SRV records.

After this is done please check DNS for the correct IP-address and SRV records.
If the DC is also Global Catlog server also check the _msdcs.kwik.com\gc zone for the correct IP-address.

Did you remember to change DNS servers referenced in your NIC settings?
