Cannot join FreeNAS 11.3-U2 to Windows Active Directory, and some troubleshooting commands fail

I need to join a FreeNAS 11.3-U2 to a Windows AD Domain however, it is failing. Following the troubleshoot commands in the user manual, some commands in particular also fail.

Top Right area of the UI (Directory Services Monitor) shows that the AD is Faulted, and LDAP & NIS disabled.

Can you please let me know what else I need to provide in the way of logs, etc?
