I think I found my problem, when configuring my second domain controller, I have created by mistake a round robin DNS entry on "Forward Lookup Zones -> ad.samdom.local". I speak of round-robin because I have two fields A pointing to the same domain Now I'm lost, you have a second domain controller in failover? If so, could you give me your DNS configuration? I need information on: Forward Lookup Zones -> ad.samdom.local. Forward Lookup Zones -> ad.samdom.local -> DomainDnsZones Forward Lookup Zones -> ad.samdom.local -> ForestDnsZones Currently I have two domain controllers in these areas (thus the round-robin). However, I have not touched the DomainDnsZones and ForestDnsZones areas, this had to be done by "samba-tool domain join" executed during installation but I'm not sure. Is it normal to have the round robin on ForestDnsZones and DomainDnsZones ? Please find attached the export of my DNS configuration. Thank you, Alexis.

I was wrong, the problem persists, it is not because of the DNS. You have the same configuration as me, but with two domains controller ?

Hi, I used the DNS management console, right click on zone and "export list". I use Bind9, and yes it is configured. Alexis.
