After disconnecting DC, FreeNAS does not connect to domain

[ewgenik]

The problem is brief: after disconnecting one of the DCs, FreeNAS does not connect to the domain.

There were two domain controllers SRV-002 and SRV-006 on Win2008. Time to upgrade to Win2019. Created two more DCs SRV-14 and SRV-41.
An hour after turning off the SRV-006, FreeNAS was rebooted, it connected to the domain, everything worked fine.
A few days later, FreeNAS was restarted again. Directory Services and CIFS do not start.

1. On FreeNAS, a new DC was clearly registered in the Directory Services settings.
Domain Controller:SRV-041
Global Catalog Server:SRV-041
Kerberos Server:SRV-041
Kerberos Password Server:SRV-041
Does not work.

2. A keytab was generated on the new DC. Configure FreeNAS to connect via keytab. Does not work.

We connected the old DC SRV-006 - everything connected and worked.

What are we doing wrong?

PS:
On FreeNAS:
grep -ri SRV-006 /var/
grep -ri SRV-006 /etc/
grep -ri SRV-006 /usr/
grep -ri SRV-006 /mnt/nas/.system/

utput is empty.

Hi ewgenik,

I've had similar issues with AD and FreeNAS in the past. You need to upgrade to the latest FreeNAS version first, there were def issues with v9 of FreeNAS and directory services.
