After some more googling and looking it appears that you will be able to run DCPROMO and it will remove the DC. But then all hell is going to break loose in your Exchange system. CAS is going to be broken along with OWA authentication.
Sorry man, but you really need to migrate the exchange off that box first.

I think you may have to migrate Exchange off of it first. Installing Exchange 2007 on Directory Servers For security and performance reasons, we recommend that you install Exchange 2007 only on member servers, and not on Active Directory directory servers. Although installing Exchange 2007 on a directory server is supported, it is strongly discouraged. However, you cannot run DCPromo on a computer running Exchange 2007. After Exchange 2007 is installed, changing its role from a member server to a directory server, or vice versa, is not supported. http://technet.microsoft.com/en-us/library/aa996719.aspx -----Original Message----- From: James Kerr [mailto:[email protected]] Sent: Friday, August 21, 2009 11:49 AM To: MS-Exchange Admin Issues Subject: demoting DC with Exchange 07 I need to demote a 08 server DC that is also running exchange 07 this weekend. Any gotchas I need to worry about or should just be a standard demotion event? The other DCs are all 03 servers, don't think that complicates anything. Thanks, James
