Question : Promote Exchange Server 2003 to Domain Controller?

I have a server 2003 domain controller (only one) and a separate exchange server 2003 on server 2003.

I would like to have 2 domain controllers on my domain and am thinking of running DCPROMO on the exchange 2003 server 2003 machine.

What are the issues involved with making an existing exchange server a domain controller?

The exchange server is a Dell Power Edge 860 with a 3ghz pentium 4 processor and 4gb of ram.  There is plenty of empty HD space.

Thanks for any suggestions you may have regarding this, either pro or con.

Couldn't find the article for some reason, but here it is now:

Quoting:

"You can run Exchange Server 2003 on either a member server or on a domain controller. After you install Exchange Server 2003 on a server, do not change the role of the server. For example, if you install Exchange Server 2003 on a member server, do not use the Dcpromo tool to promote the server to a domain controller. Or, if you install Exchange Server 2003 on a domain controller, do not use the Dcpromo tool to demote the server to a member server. Changing the role of a server after you install Exchange Server 2003 may result in loss of some Exchange functionality and is not supported."
