Microsoft Exchange Server 2007 setup cannot continue because one or more servers in the existing organization are running Exchange 2000 Server without Service Pack 3 or a later version.
Exchange 2007 setup requires that all existing Exchange 2000 Server computers in the organization be running Exchange 2000 Server Service Pack 3 (SP3).
To resolve this issue, upgrade all existing Exchange 2000 Server computers in the organization to Exchange 2000 Server SP3 or a later version, and then rerun Exchange 2007 setup.
