I didn't know I was must to use a subdomain for my Samba AD domain.
So, several years ago i set up a fancy local domain like "domain.loc".
Is this limitation written into some how to that I am lost?

So, after several years that the AD worked without problems, last week
I had to set up an new intranet web server and on AD I have add the
corresponding A record for "domain.loc" pointed to this server IP.

My Samba AD DC is master for the AD dns domain, record NS point to it,
I want change only the record A of @, not SOA or NS or MX

> so you should be pointing your AD clients at your main dns server

My all clients are already pointed to my main dns server, the AD

My DNS server is AD, then it does not need forward anything to other


a) It's possible point the A record of @, like I do on a Windows DC
server, to another server different dal DC, without after few minutes
the DC change it to itself?

b) why DC has to change this record?

This is another thing and it is relevant only if my problem occurs only
in this scenario.

Do you mean that the samba Debian version "not MIT" does NOT have this
A record substitution for @ and it's possible change it?
Many thanks for reply.
