No, you should not do that. It is not supported by Microsoft and there are known side-effects. In addition, running Exchange on domain controller, even when set up properly, can have unwanted side-effects and should be avoided when possible.

Guys, I am having one windows 2003 domain controller and one exchange 2003 server. Is it recommended to install AD on already running Exchange? Can I install AD on my EX? Is there any bad effect? Thanks, Manjeet
