Windows Server 2003 AD 升級為 Windows Server 2008 AD DS

·      Prepare your Active Directory® environment with Windows Server 2008 updates. Before you can add a domain controller that is running Windows Server 2008 to an Active Directory environment that is running Windows® 2000 or Windows Server 2003, you will need to update the environment.

To do this, you need to update the Active Directory environment by using the following procedure. If you are performing an unattended installation, perform this step before you install the operating system. Otherwise, you will need to do this after you run Setup and before you install Active Directory Domain Services.

To prepare a forest

a.   Log on to the schema master as a member of the Enterprise Admins, Schema Admins, or Domain Admins group.

b.   Copy the contents of the \sources\adprep folder from the Windows Server 2008 installation DVD to the schema master role holder.

c.   Open a Command Prompt window, navigate to the Adprep folder, and run adprep /forestprep.

d.   If you plan to install a read-only domain controller (RODC), run adprep /rodcprep.

e.   Allow the operation to complete and the changes to replicate before following the next procedure.

To prepare a domain

a.   Log on to the infrastructure master as a member of the Domain Admins group.

b.   Copy the contents of the \sources\adprep folder from the installation DVD to the infrastructure master role holder.

c.   Open a Command Prompt window, navigate to the Adprep folder, and run adprep /domainprep /gpprep.

d.   Allow the operation to complete and the changes to replicate.

After completing these steps, you can add domain controllers that are running Windows Server 2008 to the domains you have prepared. Among its tasks, the adprep command extends the schema, updates default security descriptors of selected objects, and adds new directory objects as required by some applications.
