The AD DNS zones are stored within the directory and thus Samba
replicates the content, not BIND.

This is why I couldn't understand why the OP says he has no replication.

Rowland: I set up all domain controllers bind installs the same, followed
the wiki.

Marc: that's the piece of information i needed... Now, I'll double check
this, but the other night I created a new record using the DNS snap-in from
RSAT on DC1.  After a few minutes i checked DC2's DNS zones and the record
was not visible.  I checked that drs showrepl was reporting successful
replication, it was.  Checked my sysvol rsync cron logs and they looked
fine.

How often does the DNS propagation occur?

What OS is DC1 ?
Same goes for DC2
