Active Directory Preparation Tool Prior to upgrading a Windows 2000 domain controller, you must prepare the forest and domains for the Windows Server 2003 schema modifications. The Active Directory Preparation tool (Adprep.exe) is provided to update this Active Directory forest and domain structural information. You must first prepare the forest, followed by each of the domains. Each of these processes must be run on a specific domain controller to work: . The /Forestprep process must be performed on the Schema Master. . The /Domainprep process must be performed on the Infrastructure Master for each domain. Using an account that is a member of the Enterprise Admin and Schema Admins groups for the forest root domain, you can prepare the forest by running the following command: adprep /forestprep Chapter 8 Caution Be sure to take your Schema Master offline to perform this operation. If the schema update fails, then you can log on to another domain controller in the forest root domain and seize the Schema Master role. Once the forest is prepared, you next prepare each of your domains by using the following command using an account that is a member of Domain Admins and Enterprise Admins groups: adprep /domainprep
