I understand that, I’ve tried both domain=CompanyWork and domain=CompanyWork.internal in my cred file and directly in fstab both result in the permission error when mounting the TrueNAS share but work just fine when mounting a share provided by Windows Server.

I’m assuming the domain=ip should be the IP address of the AD server right? That’s what I entered and still no luck. Same permission denied error as my past attempts.

To be fair, if someone made a blowjob machine that required an OS, it would probably be Linux. Just sayin.
