[Help] Can't join domain with F4-424 Max TOS6 6.0.750 [SOLVED]

[Tonio83]

Hi,
I've recently bought an F4-424 MAX (running TOS6 6.0.750), and I'm having difficulty joining it to my domain. I get the error: "SMB Workgroup set incorrectly!"


I've tried multiple parameters without success:

• Logon formats: [email protected], DOMAIN\user, user only

• SMB file service options: Domain name as DOMAIN, DOMAIN.LOCAL, and the default WORKGROUP

• I’ve even activated SMBv1/CIFS on my server (normally disabled for security reasons).

• I tested with a TrueNAS VM and had no issue joining the domain.

• After a factory reset, the problem still persists.

• NTP are same between the NAS & Server (same date and time).

• I've try with firewall desactivated.

My domain runs on Windows Server 2016 (with 2016 functional level).

Do you have a “magic” configuration for the NAS or any prerequisites for Windows Server 2016

Thanks you for your help

Hi.
We followed your settings but were unable to reproduce the issue in the lab.
You can try restarting the NAS and attempting the advanced settings. If the problem persists, please send the link of this post to the official website's Live Chat to schedule an engineer for remote troubleshooting.

Hi,

After a debugging session with a friend, the logs revealed two issues:

First: My domain server allows NTP connections but blocks communication.
Solution: Reset the NTP server on the domain controller.

Second: My DNS server still had records of an old and decommissioned domain server.
Solution: Delete the outdated entries.

I hope this information will be useful to help other users.
