OK, two main reasons, I have never used the internal dns server and I 
have never had any real dns problems, read a lot of posts from people 
who have, but they use the internal dns server. The second reason is 
that the internal dns server seems to ignore the SOA record for the 
second DC (note that you have to add this manually). Bind9 does see both 
SOA records and the second DC is authoritative for the domain if the 
first DC goes down for any reason, this doesn't happen with the internal 
dns server.
