How to Run Exchange Server 2003 ForestPrep
ForestPrep is run the first time you install Exchange Server 2003 into your Active Directory forest. It extends the schema to include Exchange specific classes and attributes.
Before You Begin
Before you perform the procedure in this topic, consider the following:
The account you use to run ForestPrep must be a member of the following groups:
Local Machine Administrator
When you delegate Exchange roles to a security group, it is recommended that you use Global or Universal security groups and not Domain Local security groups.
To decrease replication time, it is recommended that you run Exchange 2003 ForestPrep on a domain controller in your root domain.
