For new Forest:
. Strong password.
. Correct Network settings.
. Latest Security updates.


For Existing Forest:
. Extend Schema using adprep/forestprep
. For a windows 2000 domain adprep/domainprep /gpprep
. For a windows 2003 domain adprep/domainprep
. RODC: adprep /rodcprep

Preliminary AD DS Installation Steps



You need to consider following steps before the first Windows Server 2008 domain controller is introduced into an existing forest.

1. If the domain controller is the first Windows Server 2008 domain controller in the forest, the forest must be prepared for Windows Server 2008 by extending the schema, running adprep /forestprep, on the schema master.

2. If the domain controller is the first Windows Server 2008 domain controller in a Windows 2000 Server domain, the domain must be prepared by running adprep /domainprep /gpprep on the infrastructure master. The infrastructure master is responsible for updating references from objects in its domain to objects in other domains. At any one time, there can be only one domain controller acting as the infrastructure master in each domain.

3. If the domain controller is the first Windows Server 2008 domain controller in a Windows Server 2003 domain, the domain must be prepared by running adprep /domainprep on the infrastructure master.

4. The first Windows Server 2008 domain controller in an existing Windows 2000 Server or Windows Server 2003 domain cannot be created as an Read Only Domain Controller (RODC). After a Windows Server 2008 domain controller exists in the domain, subsequent Windows Server 2008 domain controllers can be created as RODCs. The forest and domain functional level of Windows Server 2003 is required for creating an RODC. When installing the first RODC in the forest, the forest must be prepared by running adprep /rodcprep
