We use Hapara in our district’s 1:1 program and there are many additional features to the program that make it well worth the cost in my teacher’s (and my) opinion. 75 thoughts on “ Migrating Domain Controllers From Server 2008 R2 to Server 2012 R2 ” Bandito December 19, 2013 at 9:44 am. By far the easiest and most concise. WSUS blog post Enabling a more predictable Windows Update experience for Windows 8 and Windows Server 2. KB 2. 88. 56. 94). For a more detailed explanation of some features, including their requirements, see What's New in Active Directory in Windows Server 2. R2. That means when you create a new domain on a server that runs Windows Server 2. R2, the domain functional level must be Windows Server 2. You can still add a domain controller that runs Windows Server 2. R2 to an existing domain that has a Windows Server 2. New domain and forest functional levels. There are new functional levels for Windows Server 2. R2. New features are available at Windows Server 2. R2 DFL. LDAP query optimizer changes. Performance improvement in LDAP search efficiency and LDAP search time of complex queries. Event improvements. LDAP search result statistics were added to event ID 1. Active Directory replication throughput improvement. Adjusts the maximum AD Replication throughput from 4. Mbps to around 6. Mbps. What's new in AD DS in Windows Server 2. Probably you want to use Windows Server 2008 as your default operating system, but because of the 60 day limit you haven’t installed it yet. Recently I built a new x64 or 64 Bit Windows Server 2008 machine. I wanted to install the new Virtual Machine Manager 2008; however because it was an ISO. The following table summarizes the new features for AD DS in Windows Server 2. For a more detailed explanation of some features, including their requirements, see What's New in Active Directory Domain Services (AD DS). Services running on multiple hosts can run under the same g. MSA account. Direct. Access Offline Domain Join. Extends offline domain- join by including Direct. Access prerequisites. Rapid deployment via virtual domain controller (DC) cloning. Virtualized DCs can be rapidly deployed by cloning existing virtual domain controllers using Windows Power. Shell cmdlets. RID pool changes. Adds new monitoring events and quotas to safeguard against excessive consumption of the global RID pool. Optionally doubles the size of the global RID pool if the original pool becomes exhausted. Secure Time service. Enhances security for W3. MD5 hash functions and requiring the server to authenticate with Windows 8 time clients. USN rollback protection for virtualized DCs. Accidentally restoring snapshot backups of virtualized DCs no longer causes USN rollback. Windows Power. Shell History Viewer. Allow administrators to view the Windows Power. Shell 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. 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 Connected Standby state for new device types, and consume less battery on portable devices. 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 2. Group Policy settings: Computer Configuration. GUI- based promotions are performed in Server Manager using a completely new AD DS Configuration Wizard. To simplify the installation process, ADPREP has been integrated into the AD DS installation and runs automatically as needed. The Windows Power. Shell- based AD DS Configuration Wizard automatically targets the schema and infrastructure master roles in the domains where DCs are being added, then remotely runs the required ADPREP commands on the relevant domain controllers. Error conditions can be corrected to eliminate concerns from a partially complete upgrade. The wizard also exports a Windows Power. Shell script that contains all the options that were specified during the graphical installation. For administrators that want to control the introduction of schema changes in an Active Directory forest independent of the installation of Windows Server 2. DCs in an existing forest, Adprep. It can be run remotely, and must be run remotely if that targeted operations master role is hosted on a 3. Windows Server 2. Disable the No. LMHash policy for LMHash- dependent clients as required, using the steps in KB article 9. For more information about system requirements and pre- installation information, see Installing Windows Server 2. 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. 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 2. Disk space requirements for upgrading to Windows Server 2. R2. Right sizing at deployment time is typically a good investment compared to greater touch costs required to expand disk storage after deployment. For more information, see Capacity Planning for Active Directory Domain Services. 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: In this case, you can try an offline defragmentation of the Active Directory database to recapture additional space, and then retry the upgrade. For more information, see Compact the Directory Database File (Offline Defragmentation). The Standard and Datacenter editions of Windows Server support all features and underlying hardware but vary in their virtualization rights - two virtual instances are allowed for Standard edition and unlimited virtual instances are allowed for Datacenter edition. In this case however, some Windows 8 features may require additional configuration or may not be available. For more information about those features and other recommendations for managing Windows 8 clients in downlevel domains, see Running Windows 8 member computers in Windows Server 2. You cannot upgrade domain controllers that run Windows Server 2. Windows Server 2. 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 2. Note that you cannot convert a domain controller that runs an evaluation version of Windows Server 2. 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. 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 2. Server Core installation of Windows Server 2. R2. For more information, see KB article 2. That is, before you can add a domain controller that runs Windows Server 2. Active Directory forest, the forest functional level must be Windows Server 2. This means that domain controllers that run Windows Server 2. R2, Windows Server 2. Windows Server 2. Windows 2. 00. 0 Server are not supported and will block installation of a domain controller that runs Windows Server 2. If the forest contains domain controllers running Windows Server 2. Windows 2. 00. 0, the installation is also blocked. In this case, consider the following workflow: Install domain controllers that run Windows Server 2. These domain controllers can be deployed on an evaluation version of Windows Server. This step also requires running adprep. Specifically, gracefully demote or forcibly remove Windows Server 2. Active Directory Users and Computers to remove the domain controller accounts for all removed domain controllers. The Windows Server 2. KDC support for claims, compound authentication, and Kerberos armoring. But it ensures that any domain controller in the domain runs Windows Server 2.
