samba - Nov 2016 - disable netbios = yes

hi everyone

i intend to disable netbios
could your clarify the following points for me,

do i put the following lines in my smb.conf on the domain
controllers,member server or both ?

       disable netbios = yes
       smb port = 445
       name resolv order = hosts

my member server also acts as a print server and file server
will they still function over port 445 ?

and nmbd will no longer be needed.
