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
