Louis,

       Couldn't figure out how to remove 127.0.0.53 from resolv.conf so 
I removed systemd-resolve per Rowlands post.  I then removed the 
forwarders from my smb.conf and rebooted. Nslookup partially worked as 
it used the other DC in the network to resolve and complained soldc4 
couldn't do recursive queries.  I added back in the forwarders and dns 
resolution appeared to work correctly except on soldc4. Except for one 
minor issue still remains. See output below.

@soldc4:~# nslookup soldc4
Server:         172.16.23.30
Address:        172.16.23.30#53

Non-authoritative answer:
*** Can't find soldc4: No answer

root at soldc4:~# nslookup soldc4.domain.local
Server:         172.16.23.30
Address:        172.16.23.30#53

Name:   soldc4.domain.local
Address: 172.16.23.30


The issue now is since I disabled systemd-resolve it also removed my 
search domain from resolv.conf.

@soldc4:~$ cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by 
resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual 
nameservers.
nameserver 172.16.23.30
nameserver 172.16.23.28


Where do I need to add my search domain as I already added to my netplan 
config and 50-cloud.init.yaml is the only file to config.

  ls -la /etc/netplan/
total 12
drwxr-xr-x   2 root root 4096 Aug 13 10:03 .
drwxr-xr-x 113 root root 4096 Aug 13 10:04 ..
-rw-r--r--   1 root root  584 May 28 19:36 50-cloud-init.yaml

Thanks.
