Can you expand on that ?

Your DC should be authoritative for the AD dns domain and your Domain
clients should use the DC for their DNS, anything outside the domain
should be forwarded to a DNS server outside the AD domain. This
should happen whether you use the 'internal' or 'Bind9' dns server.

This seems to be wrong, you should have the DCs IP and FQDN
shorthostname in it and '127.0.0.1 localhost'
From what you have posted, your /etc/hosts should be:

DC1:

127.0.0.1 localhost
192.168.0.251	srv1.domain.com	srv1

DC2:

127.0.0.1 localhost
192.168.0.254	srv2.domain.com	srv2

You should remove the 'domain' line, this is ignored when followed by
the 'search' line
You should replace the second nameserver with the IP of the second DC

This should be similar to the other DC, just swap the nameserver lines.
