There are differences between the way that W2K DNS does it and how
BIND does it.  The results are almost, but not quite, the same.  You need to
study W2K's update mechanism to understand the differences.

W2K's DNS does NOT follow all of the RFC's (particularly RFC 2136) in
all cases.  See the archives for details.

What documentation that has been publically made available has, so far, been
insufficient for non-Microsoft developers to implement.
