This consolidation allows for all these components to use far less system resources, work consistently, respect the new Connected Standby state for new device types, and consume less battery on portable devices. Because Windows Update is a part of Automatic Maintenance in Windows 8 and Windows Server , its own internal schedule for setting a day and time to install updates is no longer effective.
To help ensure consistent and predictable restart behavior for all devices and computers in your enterprise, including those that run Windows 8 and Windows Server , see Microsoft KB article or see October cumulative rollup , then configure policy settings described in the WSUS blog post Enabling a more predictable Windows Update experience for Windows 8 and Windows Server KB The following table summarizes new features for AD DS in Windows Server R2, with a link to more detailed information where it is available.
For a more detailed explanation of some features, including their requirements, see What's New in Active Directory in Windows Server R2.
The following table summarizes the new features for AD DS in Windows Server , with a link to more detailed information where it is available. To help ensure consistent and predictable restart behavior for all devices and computers in your enterprise, including those that run Windows 8 and Windows Server , you can configure the following Group Policy settings:. The following table lists some examples of how to configure these settings to provide desired restart behavior.
Error conditions can be corrected to eliminate concerns from a partially complete upgrade. The wizard also exports a Windows PowerShell script that contains all the options that were specified during the graphical installation. Taken together, the AD DS installation changes simplify the DC role installation process and reduce the likelihood of administrative errors, especially when you are deploying multiple domain controllers across global regions and domains.
For administrators that want to control the introduction of schema changes in an Active Directory forest independent of the installation of Windows Server DCs in an existing forest, Adprep. Beginning with Windows Server , domain controllers also have the following secure default settings, compared to domain controllers that run Windows Server or Windows For more information about system requirements and pre-installation information, see Installing Windows Server There are no additional system requirements to install a new Active Directory forest, but you should add sufficient memory to cache the contents of Active Directory database in order to improve performance for domain controllers, LDAP client requests, and Active Directory-enabled applications.
If you are upgrading an existing domain controller or adding a new domain controller to an existing forest, review the next section to ensure the server meets disk space requirements. This section covers disk space requirements only for upgrading domain controllers from Windows Server or Windows Server R2.
For more information about disk space requirements for upgrading domain controllers to earlier versions of Windows Server, see Disk space requirements for upgrading to Windows Server or Disk space requirements for upgrading to Windows Server R2.
Size the disk that hosts the Active Directory database and log files in order to accommodate the custom and application-driven schema extensions, application and administrator-initiated indexes, plus space for the objects and attributes that you will be added to the directory over deployment life of the domain controller typically 5 to 8 years. Right sizing at deployment time is typically a good investment compared to greater touch costs required to expand disk storage after deployment.
On domain controllers that you plan to upgrade, make sure that the drive that hosts the Active Directory database NTDS. DIT file before you begin the operating system upgrade. If there is insufficient free disk space on the volume, the upgrade can fail and the upgrade compatibility report returns an error indicating insufficient free disk space:.

The following Windows client and Windows Server operating systems are supported for domain member computers with domain controllers that run Windows Server or later:. You cannot upgrade domain controllers that run Windows Server or bit versions of Windows Server To replace them, install domain controllers that run a later version of Windows Server in the domain, and then remove the domain controllers that Windows Server Note that you cannot convert a domain controller that runs an evaluation version of Windows Server directly to a retail version.
Instead, install an additional domain controller on a server that runs a retail version and remove AD DS from the domain controller that runs on the evaluation version.
Due to a known issue, you cannot upgrade a domain controller that runs a Server Core installation of Windows Server R2 to a Server Core installation of Windows Server The upgrade will hang on a solid black screen late in the upgrade process.
Rebooting such DCs exposes an option in boot. An additional reboot triggers the automatic rollback to the previous operating system version. Until a solution is available, it is recommended that you install a new domain controller running a Server Core installation of Windows Server instead of in-place upgrading an existing domain controller that runs a Server Core installation of Windows Server R2.
For more information, see KB article Windows Server requires a Windows Server forest functional level. That is, before you can add a domain controller that runs Windows Server to an existing Active Directory forest, the forest functional level must be Windows Server or higher. Ensure Add a domain controller to an existing domain is checked and type the domain name in Domain:.
