If more virtual instances of Windows Server Standard are needed, each additional license of Windows Server allows up to two more virtual instances of Windows Server Standard, even though the physical server itself may have sufficient licenses for its processor chip count.
Because Windows Server Datacenter has no limit on the number of virtual instances per licensed server, only enough licenses for the physical server are needed for any number of virtual instances of Windows Server Datacenter. If the number of processor chips or virtual instances is an odd number, the number of licenses required is the same as the next even number. For example, a single-processor-chip server would still require 1 license, the same as if the server were two-processor-chip and a five-processor-chip server would require 3 licenses, the same as if the server were six-processor-chip, and if 15 virtual instances of Windows Server Standard are needed on one server, 8 licenses of Windows Server , which can cover up to 16 virtual instances, are needed assuming, in this example, that the processor chip count does not exceed In that case, the number of physical processors cannot exceed twice the number of licenses assigned to the server.

Ability to back up and restore files regardless of the permissions assigned to the folder or files. These users are unable to modify and manage permissions. Users are granted virtually no access to the system other than to use the Internet and basic applications. They are granted temporary profiles upon logon. Limited access to log on to the computer. Allows users to run applications, use local devices and peripherals but not make administrative changes.
When delegating administrative tasks, it is a good practice to create separate delegate accounts for users. The idea is to operate on the principle of least privilege, meaning for normal operations you would use a standard user account with enough access to perform your job. When elevated privileges are required, invoke the run as function or log in with your delegate account.
This reduces the risk of unintentional changes that could make for an unpleasant day for the admin. You can assign different sets of administrative responsibility to different users, and these can include segments of the directory structure such as OUs or sites. The following are several benefits of delegating administrative control:. When designing your AD DS forest structure, you should keep in mind the administrative requirements of each domain.
Each domain has the capability to contain a different OU hierarchy. The forest administrators, who are members of the Enterprise Admins group, are automatically granted the ability to create an OU hierarchy in any domain within the entire forest.
Domain administrators, who are members of the Domain Admins group in each separate domain, by default are granted the right to create an OU hierarchy within their own domain. When you initially create your OU design, you should do so to enable administration. After that, you should create any additional OUs required for the application of Group Policy and management of computers.
The final step in delegating administrative duties is identifying the toolsets available to your delegates. Microsoft has provided us with the following tools to help with administrative tasks:. Before using administrative tools, you must first ensure that the necessary access rights have been granted and that you have addressed any prerequisites, such as. Net Framework 4. 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.
