2.3 First Windows Server 2012 domain controller in an existing
forest
You can also use the AD DS Configuration Wizard to deploy
Windows Server 2012 domain controllers in a forest or domain whose
existing domain controllers are running Windows Server 2008 R2,
Windows Server 2008, or Windows Server 2003. As explained earlier in
this lesson, when you use the wizard to deploy the first Windows
Server 2012 domain controller in a domain of a forest whose domain
controllers are running earlier Windows Server versions, the Adprep
tool automatically runs to prepare the forest and domain by
extending the schema to its latest version.
The procedure that follows demonstrates this scenario by
deploying a Windows Server 2012 domain controller named
VAN-SRV-3 in a forest root domain named
fabrikam.com whose existing domain controllers
are all running Windows Server 2008 R2. After the AD DS role has
been added to server VAN-SRV-3, using the AD DS Configuration Wizard
to add the server as the first Windows Server 2012 domain controller
in the fabrikam.com forest involves the following steps:
-
On the Deployment Configuration page of the wizard, shown
in Figure 5,
select the Add A Domain Controller To An Existing Domain option,
specify fabrikam.com as the forest root domain, and specify
suitable credentials for performing the operation.
-
Proceed through the wizard as described in the previous
section until you reach the Preparation Options page shown in
Figure 6.
This page informs you that performing this operation will
prepare your forest and domain for Windows Server 2012 domain
controllers by extending the schema.If you do not want to extend
the schema, cancel the operation and do not deploy the new
domain controller.
-
Complete the remaining steps of the wizard to deploy the
domain controller and extend the schema.Note that you did not
have to manually run Adprep to prepare your forest or domain for
the domain controller running the new version of Windows
Server.
