Let me take a step back? Am I even doing this correctly? Is there an
easier method to keep multiple domains (zones) in sync? It seems there
are downsides to using DNAME records just as there are downsides to use
symlinks?
Thanks. Ryan

Ok. I see your question now. The domain names on the
right hand side need to fully qualified.
e.g. server1.domain.com.
