Thanks Carlos,

The thing is, that I did not upgrade the version of Samba - that is the next step, so the ports used would not have changed. I only updated the OS.

G'day All,

         I have 4 DCs on Centos 7.1. Everything was working really well for
years, including replication.

         Then I decided that the OS needed updating. Did the yum update on one
of the DCs, rebooted. That server is now running Centos 7.4. Samba
seemed to start okay.

         However, samba-tool drs showrepl gives this error on all 3 of the other
DCs, and shows success on the updated DC.

DC=DomainDnsZones,DC=samba4,DC=scem,DC=westernsydney,DC=edu,DC=au
         Default-First-Site-Name\SAMBA4-10 via RPC
                 DSA object GUID: 7fa7fc88-8d99-4217-b329-7e82324ec084

                 Last attempt @ Wed Mar 21 12:58:13 2018 AEDT failed, result 58
(WERR_BAD_NET_RESP)

                 10623 consecutive failure(s).
                 Last success @ Thu Mar  8 14:34:14 2018 AEDT


         Any thoughts on why this DC is now not replicating properly? Any
thoughts on how to remedy this?

You most likely will need to turn up the samba log level to get additional information but you can start with running 'yum history list all' and post results. This might help identify the changes that were made to the OS. Are you using bind or the internal DNS?
