This should not be a problem. but this was part/left over of the problem you faced friday. 

On DC1, the PTR was "somehow" deleted (whole zone was gone), at least looks like it. "CN=DELETED OBJECTS " is the trashcan in AD. 
Just verify if for both the DC's the A and PTR records are working, but that looked ok. 

The due above, somehow on DC2, the server is placed in  CN=LOSTANDFOUND, because it lots the context of the object.
When an object in AD is unknown its placed in LostAndFound. 
I'll see if i can add this in as filter to skip the deleted objects. 
samba-tool dbcheck --cross-nc --fix  can remove these or 
After the fix, just to be sure do one extra check on A/PTR records. (NS/SOA aslo) 
Your AD is not that big yet, i suggest you run: 
sudo samba-tool dns query dc1 $(hostname -d) @ ALL -U administrator
That shows all records in the zone. 

And look at the records, and same for the PTR records.
 sudo samba-tool dns query rtd-dc1 0.168.192.in-addr.arpa @ ALL -U administrator
Might be handy also if you hit strange things.

If I run Louis' "samba-check-db-repl.sh" script and it does not send an email then this is a "no news is good news" situation, I am assuming.

DC1 sends no email.

DC2 sends this:
