Microsoft Exchange Server 2007 setup cannot continue because the attempt to run the /PrepareDomain process failed. The logged on user has insufficient permissions to perform the /PrepareDomain process.

Exchange 2007 setup requires that the user who is logged on when running the /PrepareDomain process be a member of the Domain Admins group for the domain to be prepared, and a member of the Enterprise Admins group.

To resolve this issue, grant the logged-on user Domain Admins group permissions for the domain being prepared and enroll them in the Enterprise Admins groups, or log on with an account that has those permissions and rerun Exchange 2007 setup.
