Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The process of moving to Windows Server R2 might vary greatly depending on which operating system you are starting with and the pathway you take. We use the following terms to distinguish among different actions, any of which could be involved in a new Windows Server R2 deployment.
Installation is the basic concept of getting the new operating system on your hardware. Specifically, a clean installation requires deleting the previous operating system.
Upgrade means moving from your existing operating system to Windows Server R2, while staying on the same hardware. Even while staying on the same hardware, some server roles might require specific steps to ensure a smooth upgrade. For detailed information about upgrading by any of these methods to Windows Server R2, see upgrade options. Migration means moving from your existing operating system to Windows Server R2 by transferring to a different set of hardware.
Did you know that Microsoft Azure provides similar functionality in the cloud? Learn more about Microsoft Azure virtualization solutions. Before you start a clean installation of Windows Server R2, you should perform the following steps. The following are estimated system requirements for the Windows Server R2.
If your computer has less than the "minimum" requirements, you will not be able to install this product correctly. Actual requirements will vary based on your system configuration and the applications and features you install.
Consult documentation for each of the server roles you intend to deploy for more details about the resource needs of particular server roles. For the best results, conduct test deployments to determine appropriate system requirements for your particular deployment scenarios. Processor performance depends not only on the clock frequency of the processor, but also on the number of processor cores and the size of the processor cache.
The following are the processor requirements for this product:. If you create a virtual machine with the minimum supported hardware parameters 1 processor core and MB RAM and then attempt to install this release on the virtual machine, Setup will fail.
To avoid this, do one of the following: Allocate more than MB RAM to the virtual machine you intend to install this release on. Once Setup has completed, you can change the allocation to as little as MB RAM, depending on the actual server configuration. In the command prompt that opens, use Diskpart. Close the command prompt and proceed with Setup.
The following are the estimated minimum disk space requirements for the system partition. Be aware that 32 GB should be considered an absolute minimum value for successful installation. For the smallest possible installation footprint, start with a Server Core installation and then completely remove any server roles or features you do not need by using Features on Demand.
The system partition will need extra space for any of the following circumstances: If you install the system over a network. Computers with more than 16 GB of RAM will require more disk space for paging, hibernation, and dump files. To ensure that you are aware of any issues that might require workarounds, features that have been removed from the product, and features that have been added to the product, review these topics:. What's New in Windows Server R2.
You can also buy retail versions from the Microsoft Store. Before you install Windows Server R2, follow the steps in this section to prepare for the installation. Disconnect UPS devices. If you have an uninterruptible power supply UPS connected to your destination computer, disconnect the serial cable before running Setup. Setup automatically attempts to detect devices that are connected to serial ports, and UPS equipment can cause issues with the detection process.
Back up your servers. Your backup should include all data and configuration information that is necessary for the computer to function. It is important to perform a backup of configuration information for servers, especially those that provide network infrastructure, such as Dynamic Host Configuration Protocol DHCP servers.
When you perform the backup, be sure to include the boot and system partitions and the system state data. Another way to back up configuration information is to create a backup set for Automated System Recovery.
Disable your virus protection software. Virus protection software can interfere with installation. For example, it can make installation much slower by scanning every file that is copied locally to your computer.
Provide mass storage drivers. If your manufacturer has supplied a separate driver file, save the file to a floppy disk, CD, DVD, or Universal Serial Bus USB flash drive in either the root directory of the media or the amd64 folder.
To provide the driver during Setup, on the disk selection page, click Load Driver or press F6. You can browse to locate the driver or have Setup search the media. Be aware that Windows Firewall is on by default. Server applications that must receive unsolicited inbound connections will fail until you create inbound firewall rules to allow them.
Check with your application vendor to determine which ports and protocols are necessary for the application to run correctly. For all editions, you have 10 days to complete online activation, at which point the evaluation period begins and runs for days.
During the evaluation period, a notification on the Desktop displays the days remaining the evaluation period except in Windows Server Essentials. You can also run slmgr. All evaluation versions are fully functional during the evaluation period, although booting to Safe mode is not available.
The Windows Server Standard and Windows Server Datacenter editions come with the activation key pre-installed. After the day evaluation period elapses, the server warns you in various ways depending on the edition:. The operating system will shut down every hour. Windows Server Essentials: you receive warnings on the Desktop and on the dashboard, but the server does not shut down. The resulting virtual machine has the following characteristics:. The Hyper-V server role must be installed.
Download the VHD file to a convenient location. Start Hyper-V Manager. On the Action menu, point to New , and then point to Virtual Machine. After completing the New Virtual Machine wizard, check Hyper-V Manager to verify that the virtual machine was successfully created. Right-click the new virtual machine and point to Settings. In the left pane, click IDE Controller 0. In the right pane, point to Hard Drive , and then Add. In the menu that opens, click Virtual Hard Disk and point to Browse Configure the network adapter for the resulting virtual machine: right-click the virtual machine and select Settings.

It helps administrators cut down on repetitive tasks by defining prebuilt configurations that accompany PowerShell 4. Configuration parameters are saved in a Managed Object File MOF and can be used as a baseline for comparison or as a template for new deployments.
DSC is often used in the following situations:. DSC works via two basic methods: Pull and Push. The Pull method works through the use of a Pull Server. Using this method, you can configure a server as the Pull Server, which acts as central configuration repository storing the configuration data for computers. In large environments, nodes can be configured to pull from the server as they come online. The second method is the Push method.
In smaller implementations, a central server can be configured to Push DSC configurations. As an administrator, you also have the ability to use a combination of both Pull and Push methods. DSC works through the basis of defining configurations within scripts. Using Notepad, you can build a custom DSC configuration. Configurations contain several components, all of which are organized within a configuration block.
The keyword Configuration tells PowerShell that a specific configuration is to follow. Together, both of these items create the foundation of a configuration block. The basic structure of a configuration block is.
Inside the configuration block, node blocks are identified. A node represents a computer in the environment. Nodes are used when you need to apply a configuration block to a specific computer or computers.
Multiple node blocks can be created within a configuration block, although a configuration block does not have to contain any node blocks. Depending on the requirements, you might need to use node blocks. Inside the node blocks, resource blocks can be identified. Resource blocks are used to configure specific resources. These can be configured manually, or you can use several prebuilt resources available within the PowerShell framework. Some of the built-in resources include.
Resource blocks are identified by a resource name followed by an identifier. For example, to add configuration details to ensure that the Web-Server role is installed for MyComputer1 , use the following syntax:. After you have created the appropriate configurations, save it as a PowerShell script.
To invoke the configuration, execute it via an administrative PowerShell session. Invoking the configuration creates the MOF file in the working directory containing the configuration block script. To execute the configuration, run the command:. The intent of this section was to provide a high-level overview of DSC and how to use it. There are a variety of configuration parameters and best practices that go beyond the scope of this Cert Guide. In any large-scale deployment, imaging technology will be one of your strongest allies.
Microsoft has continued to evolve its imaging process through enhancements made to the Windows Deployment Services WDS role. WDS is covered in the Cert Guide , but in this section, we will assume you already have a prebuilt image and are looking to perform offline servicing of the image. So what is meant by servicing an image, and why offline? Historically speaking, updates to images required the administrator to deploy a new computer from the image, run through any customizations or updates, repackage the image, and upload it back to the repository.
This is often a lengthy process—especially when only minor updates are required. For these instances, Microsoft has provided the ability to inject updates to a Windows image file. Scenarios in which images require updating include. DISM takes the legwork out of the mix by enabling an administrator to mount the image file, similar to mounting a hard disk, and issue commands to update the image.
When the updating is complete, changes are committed to the image and the file is unmounted, in which case the image is ready for the next deployment. Some key points and best practices to consider when using DISM:. DISM is typically used for updating offline images, but it can also be used to update servers that are online especially in cases when you need a fast method to standardize or update to a higher edition of Windows.
There are several parameters you should understand when servicing images. Table outlines some of the key parameters:. Used to gather information from the image file such as index number, image name, description, and image size.
Parameter used to mount the image. When mounting the image, you must also specify an in index number or the name associated with the image.
Directory in which the image is mounted to. For optimal performance, this should be on the local computer that is updating the image. Use this switch when experiencing trouble with mounting images that might have been previously mounted. Adds one or more install packages or cabinet files.
When applying multiple packages, packages are listed in the order in which they should be installed. Adds a driver to the offline image. Produces a list of Packages from the mounted image in the mount directory. Unmounts the image. Used to change an offline windows image to a higher edition. This list is introduces only a few of the DISM parameters. The first thing you need to do is obtain a copy of the source image. In this example, we will use one of the default Windows image files found on the Server installation media and extracted by a WDS server.
To enable a feature in an offline image, perform the following steps:. Using either the index number or name of the image, mount the image to a temporary mount directory. This will extract the contents of the image Figure to a directory structure in the temp mount directory specified. This process might take time depending on the speed of your computer. Review the current state of the Remote-Desktop-Services feature.
Shown in Figure , take notice that the feature is currently disabled. Enable the Remote-Desktop-Services feature in the offline image by executing the command shown in Figure Commit changes to the image and unmount the. This will repackage the image file with the changes made.
It might take some time depending on the speed of your computer. When unmounting images, it is important to close all windows and applications, especially File Explorer windows. This will help prevent locks during the unmounting process. As discussed previously, remote management of servers is extremely helpful for an administrator, especially in scenarios in which your organization is driving a centralized management approach or if you are managing a group of Server Core installations.
Before remote management can occur, the remote servers must be configured to enable remote management. This is on by default for new installations but can be changed by navigating to the Local Server properties of Server Manager as shown in Figure Figure Server Manager Remote Management.
To enable remote management on legacy systems, you might be required to perform additional configuration steps, such as enabling WMI through the Windows Firewall service. Once enabled for remote management, use the Add other servers to manage feature from the Server Manager Dashboard.
The Add Servers dialog enables you to search for remote servers using Active Directory by importing a list from a text file or by using DNS as shown in Figure Figure Add Servers Dialog Box.
To perform a remote administrative task, such as Adding Roles and Features, highlight the remote server and right-click to bring up the list of remote management options as shown in Figure Figure Adding Roles and Features Remotely. In situations where different security boundaries—such as managing between workgroups or domains—exist, you might consider using the Manage As function to first supply the necessary authoritative credentials.
From this point, step through the Add Roles and Features Wizard as you have done previously. The only difference this time is to select the remote server previously added. To ensure the proper remote server is selected, take note of the destination server listed in the upper-right corner of the dialog box, as shown in Figure After you have installed the role, you now have the ability to manage and configure services associated with the role centrally from Server Manager on your managing server.
In addition to Server Manager, PowerShell can be another powerful tool to simplify the installation and management of server roles remotely. Using PowerShell, an administrator can perform a series of commands. Some common commands are outlined in Table Windows services have been around for some time. If you recall, a service is an application that runs in the background without a traditional user interface or requiring user interaction to complete its core function.
Services and their configurations are stored in a database known as the Service Control Database. Information is also stored under subkeys located in the Registry. Many services are installed and configured by default when the operating system or additional roles are installed. Depending on the scenario, some services require additional configuration and management. As with all administrative operations, managing services also requires the proper permissions. Members of the local administrators group, account operators, domain admins, or higher all have the ability to manage services by default.
Microsoft has provided two methods for managing services, the services. An administrator will use these methods to perform the following:.
To manage services via a GUI, use the Services. The services snap-in, as shown in Figure , can be launched by searching for services. In the instances where services need to be managed remotely from a central console, you can add the Services snap-in to a custom Microsoft Management Console.
To do this, launch the MMC application from the Search charm, add the Services snap-in to the console, and specify the name of another computer or browse to it using the Browse button as shown in Figure Figure Remote Services Management.
Regardless of local or remote, a handful of items are configurable from the Services snap-in. Each service listed has a series of configurable properties. RAM: 4 GB. Available disk space: 10 GB. When Vulnerability and Patch Management is used, at least GB of free disk space must be available. RAM: 2 GB. Available disk space: 2 GB. Download Microsoft Edge More info.
