10.9.x.xx1 is the ip of first domain controler, 10.9.x.xx2 is the ip of the second domain controler.
I notice that "domain" is not mentioned in resolv.conf ; so domain machine by short hostname is not possible for this reason ?

Please post your smb.conf and /etc/resolv.conf
You must be able to ping any domain machine by short hostname, FQDN or IP.
