Upgrade Domain Controllers to Windows Server R2 and Windows Server | Microsoft Docs.Changing a Windows Server product key | OVH Guides

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:. In this case, you can try an offline defragmentation of the Active Directory database to recapture additional space, and then retry the upgrade.

In previous releases, Windows Server editions differed in their support of server roles, processor counts and large memory support. 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.

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. This means that domain controllers that run Windows Server R2, Windows Server , or Windows Server can operate in the same forest, but domain controllers that run Windows Server are not supported and will block installation of a domain controller that runs Windows Server If the forest contains domain controllers running Windows Server or later but the forest functional level is still Windows , the installation is also blocked.

Windows domain controllers must be removed prior to adding Windows Server domain controllers to your forest. In this case, consider the following workflow:. The new Windows Server domain functional level enables one new feature: the KDC support for claims, compound authentication, and Kerberos armoring KDC administrative template policy has two settings Always provide claims and Fail unarmored authentication requests that require Windows Server domain functional level.

The Windows Server forest functional level does not provide any new features, but it ensures that any new domain created in the forest will automatically operate at the Windows Server domain functional level.

The Windows Server domain functional level does not provide other new features beyond KDC support for claims, compound authentication, and Kerberos armoring. But it ensures that any domain controller in the domain runs Windows Server After you set the forest functional level to a certain value, you cannot roll back or lower the forest functional level, with the following exceptions: after you raise the forest functional level to Windows Server , you can lower it to Windows Server R2.

If the forest functional level is set to Windows Server R2 , it cannot be rolled back, for example, to Windows Server After you set the domain functional level to a certain value, you cannot roll back or lower the domain functional level, with the following exceptions: when you raise the domain functional level to Windows Server R2 or Windows Server , and if the forest functional level is Windows Server or lower, you have the option of rolling the domain functional level back to Windows Server or Windows Server R2.

If the domain functional level is set to Windows Server R2 , it cannot be rolled back, for example, to Windows Server Beyond functional levels, a domain controller that runs Windows Server provides additional features that are not available on a domain controller that runs an earlier version of Windows Server.

For example, a domain controller that runs Windows Server can be used for virtual domain controller cloning, whereas a domain controller that runs an earlier version of Windows Server cannot. But virtual domain controller cloning and virtual domain controller safeguards in Windows Server do not have any functional level requirements.

Microsoft Exchange Server requires a forest functional level of Windows server or higher. AD DS cannot be installed on a server that also runs the following server roles or role services:. 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 Improvements in AD DS beginning in Windows Server 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. The following table covers common Active Directory-integrated Microsoft applications. The table covers what versions of Windows Server that the applications can be installed on and whether the introduction of Windows Server DCs affects application compatibility. Configuration Manager Configuration Manager Service Pack 1: Microsoft will add the following operating systems to our client support matrix with the release of Service Pack 1: – Windows 8 Pro – Windows 8 Enterprise – Windows Server Standard – Windows Server Datacenter All site server roles – including site servers, SMS providers, and management points – can be deployed to servers with the following operating system editions: – Windows Server Standard – Windows Server Datacenter Microsoft Endpoint Configuration Manager current branch Supported operating systems for Configuration Manager site system servers.

It cannot be run on a Server Core installation. It can be run on virtual servers. I recently inherited the management of a Windows server at a remote site.

It just keeps running with the progress bar cycling over and over, never getting any updates.

Try the linked Windows Update Diagnostic tool at that point, whether Windows offers it or not. MichalSokolowski “There is NO reason, on a properly functioning system, why this folder should ever need to be touched. I wanted to underline something else here; destroying Windows Update Agent patch history is really bad idea, because after deletion it lose capability to determine what was patched and what was not. In a nutshell conclusion are according to that thread : 1 deleting softwaredistribution should be treated as last resort before reformating the box, 2 deleting it need to be preceded by proper diagnosis – i.

EDB, desynchronized DataStore. EDB and Download folder – those are most common. MichalSokolowski You probably are right. Still – on every one of my systems, Windows 2k3, , R2, 7, 8, 8. I am having same problem on other people’s machines too, so it cannot be just my fault but must be some general Windows Update problem especially fresh installs of older OSs.
