Well, good question. As I am unfamiliar, I think so.
I tried Loius suggestion but got the DNS_ERROR. This is the error I am
finding alot.
Here is query and zonelist:
root at dtdc03:~# samba-tool dns query dtdc03 xxx.168.192.in-addr.arpa 49
PTR
ERROR(runtime): uncaught exception - (9714,
'WERR_DNS_ERROR_NAME_DOES_NOT_EXIST')
File
"/usr/local/samba/lib/python2.7/site-packages/samba/netcmd/__init__.py",
line 176, in _run
return self.run(*args, **kwargs)
File
"/usr/local/samba/lib/python2.7/site-packages/samba/netcmd/dns.py", line
998, in run
None, record_type, select_flags, None, None)
root at dtdc03:~# samba-tool dns zonelist dtdc03
3 zone(s) found

These three look correct, but I am not sure as I am not familiar with
this detail.
If it matters, I have two DC's but neither will reversedns. (Thought I
had this working and discovered, yesterday that one DC was not working
properly. Went through my entire setup again, on both DC's, last night
and now cannot add reversedns to either DC.) All other dns testing
checks out.
Basically I keep being told, though log files and other, that the zone
does not exist.
At this point I am a little confused but, bottom line is I cannot add
any reversedns zones to resolve my nslookup xxx.xxx.xxx.xxx failure
issue to either DC. I am puzzled.
What else would you like to see? log files?
