Hi, I am getting ready to install the Exchange Server. We are planning to Install Exchange 2003 on a Windows Server 2003 environment. Iam not sure whereto run the "Setup /forestprep" and "Setup /domainprep" do I load the Exchange Server CD on the new member server which I am installing the Exchange server or I should load the Exchange CD on the Domain Controller and run the commands "Setup /forestprep" and "Setup /domainprep". Please advice and thanks all in advance. Thanks & Regards Kuruvilla

You can run on member server where you are going to install Exchange Server, it will connect to DC/GC to extend the schema and create Exchange groups. You can follow below articles to verify How to Verify That ForestPrep and DomainPrep Completed Successfully in Exchange 2000 Server or Exchange Server 2003

When you install First Exchange Server, it will automatically run ForestPrep & DomainPrep also, it doesn't matter whether it is member server for that domain or domain controller.

Hi Kuruvilla, Actually, we can use Exchange Server Deployment Tools directly which has a more friendly interface to run Forestprep and Domainprep.The following articles for your reference.
