[Samba] New PTR records not visible

Thank you for your reply. I did check everything, and it turns out that the
DNS server nslookup was receiving its answers from is not answering
correctly.

If I specify a server, I get the correct answers, except from that one:

nslookup 192.168.10.8
** server can't find 8.10.168.192.in-addr.arpa: NXDOMAIN

nslookup 192.168.10.8 DC1
** server can't find 8.10.168.192.in-addr.arpa: NXDOMAIN

nslookup 192.168.10.8 DC2
8.10.168.192.in-addr.arpa   name = newdc.mydomain.com

nslookup 192.168.10.8 DC3
8.10.168.192.in-addr.arpa   name = newdc.mydomain.com

I verified the record on DC1:

samba-tool dns query DC1 0.0.10.in-addr.arpa 8 PTR -U Administrator
  Name=, Records=1, Children=0
    PTR: newdc.lan.cimbal.pt (flags=f0, serial=162, ttl=900) 

The record is there, but for some reason, DC1 is not answering correctly.

I won't bother sorting this out because this DC is to be retired.

Thank you again!
