SYMPTOMS

Consider the following scenario. You have a forest that includes multiple domains. One of the child domains does not include a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based domain controller. When you install Microsoft Exchange Server 2007 in the root domain, the prerequisites-checking operation does not display an error.
