Look at MS KB article 282826 (a revision of Q282826), where there is
this text:
Note The multiple-master replication behavior of an Active
Directory-integrated Domain Name System (DNS) zone can
cause inconsistencies with serial numbers of the zone
across multiple DNS servers. It is not possible to
retrieve information (pull or source) from multiple Active
Directory-integrated primary DNS servers to a secondary
DNS server for the same Active Directory-integrated zone.
This was possible and frequently done with conventional
single-master DNS. However, because serial numbers are
maintained separately on each Active Directory-integrated
DNS server, the mechanism for determining whether the
secondary DNS server has the most-recent copy may will
fail.
