OK, if you provisioned with BIND_DLZ you should find this line in smb.conf:

server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, 
winbindd, ntp_signd, kcc, dnsupdate

If you add -dns to the end of the line it may, as you have found out, 
cause problems. You should only add 'server services = -dns' if you were 
previously using the internal dns server and have upgraded to bind9 and 
DO NOT have a server services line in smb.conf. You could always add the 
entire line above instead, after you upgrade to Bind9.
