We have one installation of Zabbix server (version 6.2.1) with 186 hosts configured.
We installed a new domain controller with Windows Server 2019 and then proceed with the dismiss of the old domain controllers (Windows server 2016).
When we turn off one of the old domain controllers, the Zabbix message queues fill up and the host unreachable emails start to arrive.
We have 2 domain controllers 2016 and the problem occurs when we switch off one of them indifferently.
Hosts in zabbix are configured via IP, not dns queries.
