I have problems with my DC and DNS server

we configured a DC with its corresponding DNS server long time ago.
This server has been used simply as a file server, without the need to join any computer to the domain.
The problem is now that we want to separate the domain from the file server. When we trying to join another secondary DC, we realized that we should not have configured something correctly in the DNS because we cannot join computers in the domain, much less introduce a second DC.
We have done a lot of tests and checked a lot of things. We are very lost right now.
I think the problem may come from a result that dcdiag /test:dns gives me and is that it does not find the "a" record of the server itself in the DNS, when it OBVIOUSLY exists.
Do you recommend recreating the entire DNS?
Any suggestions that I can keep checking out?

thanks in advance

Login on your DC and run the following commands:

Dcdiag /v /c /d /e /s:%computername% >C:\Temp\dcdiag_%computername%.log
repadmin /showrepl >C:\Temp\repl_%computername%.txt
ipconfig /all > C:\Temp\ipconfig_%computername%.txt
dcdiag /v /test:dns > C:\Temp\dcdiag_%computername%.txt

Hello cthivierge,

I will share you a link later.

Yesterday we fixed the DNS, we think so.

Now we are trying to join a second DC, but we have a new issue.
"file name directory name or volume label syntax is incorrect"

Does your 2nd DC has been added as been joined to the domain as a member server before trying to promote it as a DC?

Please run this command on the 2nd DC

ipconfig /all > C:\Temp\ipconfig_%computername%.txt

then put unzipped text files up on OneDrive and share a link
