DomainPrep creates the groups and permissions necessary for Exchange servers to read and modify user attributes in Active Directory. You must run DomainPrep before installing your first Exchange server in a domain.

Before You Begin
Before you perform the procedure in this topic, consider the following:
-
Before you run DomainPrep, you must have run ForestPrep in the forest.

Before you run DomainPrep, make sure the schema changes made during ForestPrep have replicated throughout the forest.
-
The account you use to run DomainPrep must be a member of the following groups:
-
Domain Administrators for the local domain
-
Local Machine Administrator
-
You must run DomainPrep in the following domains
-
The root domain.
-
All domains that will contain Exchange 2003 servers.
-
All domains that will contain Exchange Server 2003 mailbox-enabled objects (such as users and groups), even if no Exchange servers will be installed in these domains.
-
All domains that contain global catalog servers that Exchange directory access components may potentially use.
-
All domains that will contain Exchange 2003 users and groups that you will use to manage your Exchange 2003 organization.
-
You do not need any Exchange permissions to run DomainPrep
