Quite correct, each DC running a dns server is authoritative for the dns
domain, try this on each DC:

host -t soa samdom.example.com

It should return something like this:

samdom.example.com has SOA record dc4.samdom.example.com. hostmaster.samdom.example.com. 2455 900 600 86400 3600

The only difference between the DC's should be the short hostname.
