The local domain needs to be updated
Topic Last Modified: 2007-03-27
Microsoft Exchange Server 2007 setup cannot continue because the logged on user does not have the account permissions that are required for domain preparation.
Exchange setup requires that the user who is logged on when Setup /PrepareDomain is run be a member of the Domain Administrators and Exchange Organization Administrators groups, or the Enterprise Admins group.
To resolve this issue, grant the logged on user Domain Admins and Exchange Organization Administrator permissions, enroll them in the Enterprise Admins group, or log on with an account that has those permissions and rerun Exchange 2007 setup.
