Hai, 
 
Well. This is and discussion point. I start with...  Its not faulty. 
 
but why o why are you running a AD DC server with DHCP IP numbers. 
Really setup you DC's with static ip's.
 
What happens when you DHCP server errors, you dont notice this, and you dc wants a renewal... test this.  
I'll bet your server wont like it. 
 
Now, also check this one, i need to add this also in the test scripts. 
 
systemctl cat samba-ad-dc
If you see : After=network.target   and what i suspect, you will. 
 
now, you have 2 options to edit a systemd service file. 
1) systemctl edit samba-ad-dc.service  , this creates an override.d folder for samba-ad-dc. in /etc/systemd/system.   
    You get a blank file you need to fill..  
2) systemctl edit --full samba-ad-dc.service  this creates a copy of the full original file, in /etc/systemd/system.  
    This is what i preffer.
 
Now change 
After=network.target
to 
After=network-online.target bind9.service ntp.service
 
This makes sure bind9 and ntp are loaded ( when installed) before samba and now samba also waits until all network interfaces are online.
 

This is how i suggest you should setup your interfaces, but .. hee its your server..  ;-)  if you like dhcp setups, thats up 2 you. 
and dont forget to change eth if needed. 
 
 /etc/network/interfaces
# The loopback interface
auto lo
iface lo inet loopback
 
auto eth0
iface eth0 inet static
    address 10.44.1.9
    netmask 255.255.0.0
    gateway 10.44.1.1

with resolv.conf like this. 
search ry11cit.lan
nameserver 10.44.1.9
nameserver 10.44.1.10
# Optional, fallback for internet if both (samba-ad-dc) are down.
#nameserver 8.8.8.8

and the other DC
 /etc/network/interfaces
# The loopback interface
auto lo
iface lo inet loopback
 
auto eth0
iface eth0 inet static
    address 10.44.1.10
    netmask 255.255.0.0
    gateway 10.44.1.1

with resolv.conf like this. 
search ry11cit.lan
nameserver 10.44.1.10
nameserver 10.44.1.9
# Optional, fallback for internet if both (samba-ad-dc) are down.
#nameserver 8.8.8.8
