Is it possible to change a DC name? as I could not see an option/argument
to change using the classicupgrade.
Everything works well except for the DNS which I need to point to the samba
server for every machine clients (in my windows clients, I manually point
it to 192.168.254.254).
samba-tool domain classicupgrade --dbdir=/usr/local/samba-dec2019/private
--realm=lumad.sandbox.net --dns-backend=SAMBA_INTERNAL /srv/samba/smb.conf
root at lumad-dc1 lumad2019]# samba-tool domain info 192.168.254.254
Forest : lumad.sandbox.net
Domain : lumad.sandbox.net
Netbios domain : LUMAD
*DC name : lumad-dc1.lumad.sandbox.net
DC netbios name : LUMAD-DC1
Server site : Default-First-Site-Name
Client site : Default-First-Site-Name
We have DHCP server that automatically assigned the default DNS and I don't
have access over those servers however it already configured to point
<http://lumad-dc1.sandbox.net>* in our DNS servers but not to
<http://lumad-dc1.lumad.sandbox.net>* as I got after the upgrade.
In the client, I got this issue...

DNS was successfully queried for the service location (SRV) resource record
used to locate a domain controller for domain "lumad-dc1.lumad.sandbox.net":
The query was for the SRV record for _ldap._tcp.dc._
The following domain controllers were identified by the query:
However no domain controllers could be contacted.
Common causes of this error include:
- Host (A) or (AAAA) records that map the names of the domain controllers
to their IP addresses are missing or contain incorrect addresses.
- Domain controllers registered in DNS are not connected to the network or
are not running.
Hope someone can give insight into what possible option during the
classicupgrade or alter the samba DNS (current setup) to point to
