Applies To: Windows Server 2016, Windows Server 2012 R2, Windows Server 2012 This topic provides background information about Active Directory Domain Services in Windows Server 2012 R2 and Windows Server 2012 and explains the process for upgrading domain controllers from Windows Server 2008 or Windows Server 2008 R2. • • • • • • • • • • • • • • • Domain controller upgrade steps The recommended way to upgrade a domain is to promote domain controllers that run newer versions of Windows Server and demote older domain controllers as needed. That method is preferable to upgrading the operating system of an existing domain controller. This list covers general steps to follow before you promote a domain controller that runs a newer version of Windows Server: • Verify the target server meets. • Verify security settings.
For more information, see and. • Check connectivity to the target server from the computer where you plan to run the installation. • Check for availability of necessary operation master roles: • To install the first DC that runs Windows Server 2012 in an existing domain and forest, the machine where you run the installation needs connectivity to the schema master in order to run adprep /forestprep and the infrastructure master in order to run adprep /domainprep. • To install the first DC in a domain where the forest schema is already extended, you only need connectivity to infrastructure master.

The first two editions released by Microsoft are Windows XP Home Edition, designed for home users, and Windows XP Professional, designed for business and power users.
• To install or remove a domain in an existing forest, you need connectivity to the domain naming master. • Any domain controller installation also requires connectivity to the RID master. • If you are installing the first read-only domain controller in an existing forest, you need connectivity to the infrastructure master for each application directory partition, also known as a non-domain naming context or NDNC. • Be sure to supply the necessary credentials to run the AD DS installation.
Installation action Credential requirements Install a new forest Local Administrator on the target server Install a new domain in an existing forest Enterprise Admins Install an additional DC in an existing domain Domain Admins Run adprep /forestprep Schema Admins, Enterprise Admins, and Domain Admins Run adprep /domainprep Domain Admins Run adprep /domainprep /gpprep Domain Admins Run adprep /rodcprep Enterprise Admins You can delegate permissions to install AD DS.

New features listed by server role and technology area are listed in the following table.
For more whitepapers, video demonstrations, and presentations about other features in Windows Server 2012, see. Automatic Maintenance and changes to restart behavior after updates are applied by Windows Update Prior to the release of Windows 8, Windows Update managed its own internal schedule to check for updates, and to download and install them. It required that the Windows Update Agent was always running in the background, consuming memory and other system resources.
Windows 8 and Windows Server 2012 introduce a new feature called. Automatic Maintenance consolidates many different features that each used to manage its own scheduling and execution logic. This consolidation allows for all these components to use far less system resources, work consistently, respect the new 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 2012, 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 2012, see Microsoft KB article (or see October 2013 cumulative rollup ), then configure policy settings described in the WSUS blog post. What's new in AD DS in Windows Server 2012 R2?
The following table summarizes new features for AD DS in Windows Server 2012 R2, with a link to more detailed information where it is available. For a more detailed explanation of some features, including their requirements, see. Feature Description Allows information workers to join their personal devices with their company to access company resources and services.
Provides access to web application using a new Remote Access role service. AD FS has simplified deployment and improvements to enable users to access resources from personal devices and help IT departments manage access control. Domain Controllers running Windows Server 2012 R2 block the creation of duplicate service principal names (SPNs) and user principal names (UPNs). Enables lock screen applications to be restarted and available on Windows 8.1 devices. Enables CAs to cryptographically attest in an issued certificate that the certificate requester private key is actually protected by a Trusted Platform Module (TPM). New credential protection and domain authentication controls to reduce credential theft.
The Windows Server 2003 domain functional level is also deprecated because at the functional level, FRS is used to replicate SYSVOL. That means when you create a new domain on a server that runs Windows Server 2012 R2, the domain functional level must be Windows Server 2008 or newer. You can still add a domain controller that runs Windows Server 2012 R2 to an existing domain that has a Windows Server 2003 domain functional level; you just can't create a new domain at that level. There are new functional levels for Windows Server 2012 R2.
New features are available at Windows Server 2012 R2 DFL. Performance improvement in LDAP search efficiency and LDAP search time of complex queries. LDAP search result statistics were added to event ID 1644 to aid in troubleshooting. Adjusts the maximum AD Replication throughput from 40Mbps to around 600 Mbps What's new in AD DS in Windows Server 2012?
The following table summarizes the new features for AD DS in Windows Server 2012, with a link to more detailed information where it is available. For a more detailed explanation of some features, including their requirements, see. Feature Description Active Directory-Based Activation (AD BA) see Simplifies the task of configuring the distribution and management of volume software licenses. Adds role install via Server Manager, simplified trust-setup, automatic trust management, SAML-protocol support, and more. Active Directory lost page flush events NTDS ISAM event 530 with jet error -1119 is logged to detect lost page flush events to Active Directory databases. Active Directory Administrative Center (ADAC) adds GUI management of recycle bin feature originally introduced in Windows Server 2008 R2. Supports the creation and management of Active Directory sites, site-links, connection objects, and more using Windows PowerShell.
New claims-based authorization platform that enhances the legacy access control model. ADAC adds GUI support for the creating, editing and assignment of PSOs originally added in Windows Server 2008. A new security principal type known as a gMSA. Services running on multiple hosts can run under the same gMSA account. Extends offline domain-join by including DirectAccess prerequisites. Virtualized DCs can be rapidly deployed by cloning existing virtual domain controllers using Windows PowerShell cmdlets. Adds new monitoring events and quotas to safeguard against excessive consumption of the global RID pool.

Secure Time service Enhances security for W32tm by removing secrets from the wire, removing the MD5 hash functions and requiring the server to authenticate with Windows 8 time clients Accidentally restoring snapshot backups of virtualized DCs no longer causes USN rollback.
Allow administrators to view the Windows PowerShell commands executed when using ADAC. Automatic Maintenance and changes to restart behavior after updates are applied by Windows Update Prior to the release of Windows 8, Windows Update managed its own internal schedule to check for updates, and to download and install them. It required that the Windows Update Agent was always running in the background, consuming memory and other system resources. Windows 8 and Windows Server 2012 introduce a new feature called. Automatic Maintenance consolidates many different features that each used to manage its own scheduling and execution logic.
This consolidation allows for all these components to use far less system resources, work consistently, respect the new 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 2012, its own internal schedule for setting a day and time to install updates is no longer effective. Note Microsoft Exchange Server 2013 requires a forest functional level of Windows server 2003 or higher.
AD DS interoperability with other server roles and Windows operating systems AD DS is not supported on the following Windows operating systems: • Windows MultiPoint Server • Windows Server 2012 Essentials AD DS cannot be installed on a server that also runs the following server roles or role services: • Hyper-V Server • Remote Desktop Connection Broker Operations master roles Some new features in Windows Server 2012 affect operations master roles: • The PDC emulator must be running Windows Server 2012 to support cloning virtual domain controllers. There are additional prerequisites for cloning DCs. For more information, see.
• New security principals are created when the PDC emulator runs Windows Server 2012. • The RID Master has new RID issuance and monitoring functionality. The improvements include better event logging, more appropriate limits, and the ability to - in an emergency - increase the overall RID pool allocation by one bit. For more information, see.
Note Though they are not operations master roles, another change in AD DS installation is that DNS server role and the global catalog are installed by default on all domain controllers that run Windows Server 2012. Virtualizing domain controllers Improvements in AD DS beginning in Windows Server 2012 enable safer virtualization of domain controllers and the ability to clone domain controllers. Cloning domain controllers in turn enables rapid deployment of additional domain controllers in a new domain and other benefits. For more information, see. Administration of Windows Server 2012 servers Use the to manage domain controllers and other servers that run Windows Server 2012.
