     No...  I'll try that now.  Okay....  No good.  Here is what happens 
- the point where it fails varies:

samba-tool domain join SAMBA4.SCEM.UWS.EDU.AU DC -Uadministrator 
--realm=SAMBA4.SCEM.UWS.EDU.AU --dns-backend=SAMBA_INTERNAL 
--domain-critical-only --site=samba4-01

Found DC samba4-02.samba4.scem.uws.edu.au
