I am trying to install Exchange 2010 on a new server. We currently have Exchange 2003 installed on another server, and Windows 2003
domain controller(s). At one point I did have a test exchange 2007 server installed that is no longer online due to a hardwre failure.  I am getting the error:

Coexistence between Exchange Server 2010 and Exchange Server versions older than Exchange Server 2007 SP2 in the same Active Directory Site is not supported.
