First up, is this an AD Directory service, or the 'classic' samba domain

The reasons are more philosophical than technical. For an appliance
like FreeNAS, if you were ever to use that as an AD DC, then perhaps the
organisation is so small that there is only one machine, and that would
be fine. But if the organisation was running multiple servers, I would
suggest running two as the AD DC, and provisioning file servers

No, it shouldn't lock up.

Nobody should be using the NTVFS server in new installations without a
very, very good reason. However, changing over is just a matter of
using the 'samba-tool ntacl sysvolreset' tool, assuming only the sysvol
share is in use.
