Add IPv6 to PfSense, DNS problems IPv4

I agree. How do we fix this? :)
ON DC01, "format c:".
It's a Windows problem, not pfSense. You'll have to see what's wrong with your own system. We can't do it for you.

I am not sure how to troubleshoot this using WireShark. I could run it on DC01. Could you tell me what to do and what to look for?
Are you the admin for the domain controller? If so. I'd have to question your abilities. Filter on ICMP6 and watch for DHCPv6. It works just like DHCP on IPv4, in the sequence of packets, though the contents are different.

I didn't know a domain controller is a niche thing.
There are plenty of people who are familiar with Windows, myself included. However, most of those people have no exposure to Windows domain controllers, myself included. The closest I got to that was when I was doing Windows desktop support at IBM 17 years ago, and reset user passwords. Now, if you wanted to set up a file & print or IMAP server on Linux, I may be able to help.

Make double sure that IPv6 is enabled on the network adapter on DC01, and then make sure that "Obtain IP address automatically" is checked on the IPv6 Properties tab as well. Alternatively, you can assign a static IPv6 address from your subnet. That is actually preferred for a domain controller, especially one that is also the DNS server for the domain. Best practice for domain controllers is to always assign them static IP addresses (both IPv4 and IPv6).
If all that is set correctly, go here, read the information, and then examine the Registry of your domain controller to see if someone in the past disabled IPv6 using the Registry settings described in the link I provided. If you find they did, then use the information at the link to put things back to "normal" so IPv6 works.
But you really should use static IP addresses for domain controllers!

Exactly! especially if they are going to be dhcp servers, normally the dhcpv4 would normally be your v6 dhcp server as well - if your using it.
