Preparing Active Directory

Before installing Exchange I need to update the Active Directory Schema.  This is done by running the following command on a domain controller:

D:\Setup.Com /PrepareAD /OrganizationName: MyCompany

Where D: is the drive that contains the installation DVD and MyCompany is the name to be used for the Exchange organisation.  Here is a screenshot of this process in action:

I’m running this on a DC because the process requires LDIFDE and this isn’t installed on the Exchange server (although I could easily install it).  The user account I’m logged on with is an administrator that is a member of the Enterprise Admins and Scheme Admins groups.
