Microsoft Exchange Server 2007 Setup cannot continue the installation because the target computer is a Read-Only Domain Controller (RODC).

Read-Only Domain Controllers are a feature of Windows Server 2008 Active Directory. The RODC is a type of domain controller install option that can be installed in remote sites that may have lower levels of physical security.

Exchange Setup requires write access to the target install computer.

To resolve this issue, select a target install computer that is not designated as an RODC, and rerun Setup.
