The only problem I can see from your set up is the 'dns forwarder' line
in your smb.conf , it appears to be pointing at your other DCs and it
should point to nameservers outside your AD dns domain e.g. Googles

I take it that you have tried restarting the DC and that a firewall
isn't getting in the way.
I also take it that you have installed all the required Samba packages.
