You need to add the member servers DNS record to the AD DC, Unix doesn't 
add them automatically. What is your AD DC, a windows one or a Samba4.

Add:
     # disable printing completely
     load printers = no
     printing = bsd
     printcap name = /dev/null
     disable spoolss = yes

To smb.conf and then restart Samba.
