Although I am just a humble professional, I feel that simple things should be kept simple. The very reason that IIS should not be kept on a DC machine is provided by Microsoft itself: the Web Edition of their 2003 Server.
Aside from that, there's a lot to do with your design: I mean you can have a DMZ; I mean c'mon, if someone manages to hack your public network, the private one is still isolated. That is for the Web server that is exposed.
My guess is that you can put IIS on a domain controler if and only if the server is inside your private network and you are running some n-tier system and you have a tight budget. So much for the Web server that is not exposed (inside your private network).
