Microsoft Exchange Server 2007 setup cannot continue because one or more servers in the existing organization are running Exchange Server 2003 without Service Pack 2 (or a later version).

Exchange 2007 setup requires that all existing Exchange Server 2003 computers in the organization be running Exchange Server 2003 Service Pack 2 (SP2) or a later version.

To resolve this issue, upgrade all existing Exchange Server 2003 computers in the organization to Exchange Server 2003 SP2 or a later version, and then rerun Exchange 2007 setup.

For more information about upgrading Exchange Server 2003 computers to Exchange Server 2003 SP2 or a later version, see "Downloads for Exchange Server 2003" (http://go.microsoft.com/fwlink/?LinkId=21030).
