Why is there 'DC02' at the end ? you should remove it.

Unmask 'winbind', but you shouldn't start Samba until you have joined

Is 'DC01' your netbios domain name (aka workgroup) ?

It has joined the domain.

You have dns problems, fix /etc/hosts, check that /etc/hostname only

Properly set up, this would be okay.

If you are running a second DC, you are running an additional dns
server, every Samba DC runs the internal dns server. Also every Samba
DC should use its own ipaddress for its nameserver.

That is NEVER going to work, every DC and domain member in the domain
must use the same dns domain name, in your case, this seems to be
'test-server.lan'. The realm would then be the dns domain in uppercase

I would get the domain working correctly before adding CNAME records
(which is what you seem to want to do), though there is little reason
to do this.
