Mark Lahn February 19, Computers running bit processors can hypothetically handle hundreds of terabytes of RAM. For example, it can make installation much slower by scanning every file that is copied locally to your computer. This is often a lengthy process—especially when only minor updates are required.

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. As you can see, several configurable items are grouped into different tabs as outlined in Table Used to configure the account used to start the service upon boot up.

In most cases, this is defaulted to the Local Service or System built in accounts. If a specific account has been delegated the ability to run the service, this tab provides the ability to supply the authoritative credentials. Commonly used SC commands are listed in Table Queries a server for Service Status. Creates a new service in the Service Control Managers database. The startup type, location to the binary path, display name, and so on are among the configuration options for this command.

These are only a few of the options available for the SC command. Multiple network interface cards are joined together and operate as a single entity. Previously, NIC Teaming was left for the manufacturers to provide a tool. From the NIC Teaming interface, highlight the available adapters to be added to the team as shown in Figure Confirm that all appropriate adapters are checked.

Figure New Team Dialog Box. Expand the Additional Properties drop-down and choose the appropriate Teaming mode.

The following modes can be selected:. This is the most common teaming method as it supports just about any Ethernet switch. The passive links stand by and take over during a failover event resulting from the active link failing. The use of enterprise classed managed switches is required.

After you have successfully configured a NIC Team, a new logical adapter will be available for management under the Network and Sharing Center. From here, you can manage adapter settings much like you have done previously with a traditional adapter. There are many scenarios and configurations for NIC Teaming. To create a new NIC Team, execute the following command:. To remove the NIC Team, execute the command:.
