 * Hello, I admin a whole lot of varied web sites, on varied systems, under the 
   umbrella of [http://www.birds.cornell.edu](http://www.birds.cornell.edu) and 
   I want to add WordPress to the mix. So far it’s gone well but I’m having trouble
   integrating a new site into the topology and I could use some help and advice.
 * I have WP 3.1.3 running as a network, and it’s on the same server as a number
   of other sites, but running on its own IP. Since we don’t want WP to serve our
   home page, I have got WP installed so that the root is named [http://www.birds.cornell.edu](http://www.birds.cornell.edu)
   but it doesn’t really live at that address; traffic gets routed to the various
   WP blogs through IIS proxying rewrites. This works well, and appears seamless
   so it looks like the blogs are living under the proper address. I also have a
   non-public service address [http://www.ornithopolis.org](http://www.ornithopolis.org)
   mapped to the IP that WP is using, so I can bypass the rewrites if necessary.
   I also have WordPress MU Domain Mapping installed, but I haven’t tried to use
   it until today
 * Today, we wanted to launch a new project, content.yardmap.org and point it to
   a blog running on [http://www.ornithopolis.org](http://www.ornithopolis.org) 
   under a MU domain mapping. I set this up on a test server and it works just fine:
   supertest.yardmap.org really lives at test.ornithopolis.org and it works seamlessly.
   However when I tried to set this up on the live server, I got a 404 error. Somehow,
   the configuration that includes the mapping to [http://www.birds.cornell.edu](http://www.birds.cornell.edu)(
   which is unrelated to this blog, but necessary to other blogs on the network)
   is causing it to get confused. Any suggestions on how I can untangle this?

 * So you have a master network at [http://www.birds.cornell.edu](http://www.birds.cornell.edu)
   and made a subsite called (let’s say) [http://www.birds.cornell.edu/ornithopolis](http://www.birds.cornell.edu/ornithopolis)
 * Then you put in domain mapping to point [http://www.ornithopolis.org](http://www.ornithopolis.org)
   to [http://www.birds.cornell.edu/ornithopolis](http://www.birds.cornell.edu/ornithopolis)
 * Is that right?

 * Not quite. The WP install “lives” at the IP address that’s mapped to ornithopolis.
   org, but the site that it serves is underneath [http://www.birds.cornell.edu](http://www.birds.cornell.edu),
   so the root of the network is at [http://www.birds.cornell.edu](http://www.birds.cornell.edu),
   and traffic gets to/from it via a proxy rule in IIS. So I can set up /blog and
   it will appear at ornithopolis.org/blog, and with a rule to proxy ^/blog(.*) 
   it will also appear at [http://www.birds.cornell.edu/blog](http://www.birds.cornell.edu/blog)
   and work beautifully.
 * The problem occurs when I want to map a new domain, in this case yardmap.org,
   to that blog. If I set up the cname to point to [http://www.birds.cornell.edu](http://www.birds.cornell.edu),
   it’ll go to the IIS main server instead of WP and the main server won’t have 
   the mapping. If I point the cname to ornithopolis.org, WP returns a 404.
