[Samba] Can't connect via smb to s4 DC

[Arthur Ramsey]

I have 4 samba 4.5.0 DCs.  I can connect via smb to two of them and 
can't connect to another two.  I get an error "The request is not 
supported".  Those same two DCs I cannot connect to via smb also have 
issues via ADUC.  I get an "RPC server is unavailable" when trying to 
connect with ADUC.

Here's my smb.conf: http://pastebin.com/7J8hNd0Y.

Thanks,
Arthur
