But it can be found via DNS, why changing local (for this server) 
hostname affects this?
How to fix it right?

No, it'a a DC server and it never use a DHCP.

Ok, I'll try this
But wiki for example 
https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory) 
suggest to add hostname to /etc/hosts:

"Verify that the host name in /etc/resolv.conf resolves to the network 
IP and not to 127.0.0.1 (localhost)."

It only for precondition before join and may be deleted after?
