Preparing your Active Directory infrastructure for upgrade to Windows Server includes the following tasks: Prepare Windows Server forest schema for a domain controller that runs Windows Server Prepare Windows Server domain for a domain controller that runs Windows Server Note: Review the list of operations that Adprep. There should not be any conflicts if your applications use RFC-compliant object and attribute definitions.
For a list of specific operations that are performed when you update the Active Directory schema, see Appendix of Changes to Adprep. You can also test the Active Directory upgrade in a test environment with all the applications configured for testing purposes. Forest Schema preparation Before you can add a domain controller that is running Windows Server to an Active Directory environment that is running Windows Server or Windows Server , you must update the Active Directory schema.
You must update the schema from the domain controller that hosts the schema operations master role also known as flexible single master operations or FSMO. For normal installations, you must update the schema after you run Setup and before you install AD DS. Membership in Enterprise Admins, Schema Admins, and Domain Admins for the domain that contains the schema master is required to complete this procedure.
Review details about using the appropriate accounts and group memberships at http: Open a command prompt, and then change directories to the Adprep folder. Domain Schema preparation After you prepare the forest, you need to prepare any domain for which you plan to install a domain controller that runs Windows Server Use the following procedure to prepare a Windows or Windows Server domain for Windows Server Membership in Domain Admins, or equivalent, is the minimum required to complete this procedure.
To prepare a Windows domain for Windows Server Identify the domain infrastructure operations master role holder as follows: In the Active Directory Users and Computers snap-in, right-click the domain object, click Operations Masters, and then click Infrastructure. Log on to the infrastructure master as a member of the Domain Admins group. After the forest and domain based schema is prepared, new Windows Server based domain controllers can be added to the domain.
You can install AD DS on any Windows Server —based member server that meets the domain controller hardware requirements. Click Start, click Run, type dcpromo. Membership in the local Administrator account, or equivalent, is the minimum required to complete this procedure. Click Start, and then click Server Manager. In Roles Summary, click Add Roles. If necessary, review the information on the Before You Begin page, and then click Next.
If necessary, review the information on the Active Directory Domain Services page, and then click Next. On the Confirm Installation Selections page, click Install. If you want to install from media, or identify the source domain controller for AD DS replication as part of the installation of the additional domain controller, click Use advanced mode installation.
On the Operating System Compatibility page, review the warning about the default security settings for Windows Server domain controllers, and then click Next. On the Choose a Deployment Configuration page, click Existing forest, click Add a domain controller to an existing domain, and then click Next.
On the Network Credentials page, type the name of any existing domain in the forest where you plan to install the additional domain controller. Under Specify the account credentials to use to perform the installation, click My current logged on credentials or click Alternate credentials, and then click Set.
In the Windows Security dialog box, provide the user name and password for an account that can install the additional domain controller.
To install an additional domain controller, you must be a member of the Enterprise Admins group or the Domain Admins group. When you are finished providing credentials, click Next. On the Select a Domain page, select the domain of the new domain controller, and then click Next. On the Select a Site page, select a site from the list or select the option to install the domain controller in the site that corresponds to its IP address, and then click Next.
On the Additional Domain Controller Options page, make the following selections, and then click Next: This option is selected by default so that your domain controller can function as a DNS server. If you are installing an additional domain controller in either the forest root domain or a tree root domain, you do not have to create the DNS delegation. In this case, click Yes and disregard the message. This option is selected by default.
It adds the global catalog, read-only directory partitions to the domain controller, and it enables global catalog search functionality. This option is not selected by default. It makes the additional domain controller read only. If you selected Use advanced mode installation on the Welcome page, the Install from Media page appears. You can provide the location of installation media to be used to create the domain controller and configure AD DS, or you can have all the replication done over the network.
Note that some data will be replicated over the network even if you install from media. If you selected Use advanced mode installation on the Welcome page, the Source Domain Controller page appears.
Click Let the wizard choose an appropriate domain controller or click Use this specific domain controller to specify a domain controller that you want to provide as a source for replication to create the new domain controller, and then click Next.
If you do not choose to install from media, all data will be replicated from this source domain controller. Windows Server Backup backs up the directory service by volume. For backup and recovery efficiency, store these files on separate volumes that do not contain applications or other nondirectory files.
On the Summary page, review your selections. Click Back to change any selections, if necessary. To save the settings that you have selected to an answer file that you can use to automate subsequent Active Directory operations, click Export settings.
Type the name for your answer file, and then click Save. You can either select the Reboot on completion check box to have the server restart automatically or you can restart the server to complete the AD DS installation when you are prompted to do so.
