As an organization grows, administration of servers can become become quite overwhelming to manage. To help balance the workload and create a smooth support process, a delegation model should be implemented. Implementing a delegation model involves the following:. Preparing for a delegation model requires some planning up front. Deciding how to manage your systems administration can be a frustrating task.
The key to success is to define a model that best works for your situation, agree upon the long-term strategy, and discipline those involved to stick with the model. There are three basic strategies to select from when deciding how to manage your environment:.
Containing characteristics of both decentralized and centralized models, the shared or delegated approach focuses on centralized policies and procedures governed by the enterprise admins.
This approach is hierarchical in nature in that many layers of administration can be defined. For example, the main office might contain the majority of the systems. These systems are managed by senior administrators or an enterprise admin group. Desktop engineers might be delegated administrative access to all desktops but might escalate issues to site admins or even enterprise admins if necessary.
Once a delegation model has been selected, the next step is to decide how to delegate access. Depending on the server, installed roles, and applications installed, there are different ways to delegate access. In some cases, applications or roles include an interface where elevated access is granted. In most other situations, local built-in groups can be used to grant different access to different delegates depending on their function.
For example, suppose you have delegated backup duties to a small team of junior administrators. To help streamline this in larger organizations, you might consider additional layers of group nesting along with group policy to push down the elevated access to a group of servers.
This method provides a more scalable solution as expanding delegate access is as simple as adding more junior admin accounts to a domain group. The domain group is then automatically added to the backup operators local group on the servers. Active Directory will be discussed in more detail later. Refer to Table for a listing of built-in local groups and their functions. Grants full access and control to the computer.
Allows members to change and manage permissions and access to the computer. 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. Throw a 32GB boot drive in my Intel Atom based pfsense appliance and the minimum specifications have been exceeded!
I can tell you, Windows Server R2 on the Atom is a painful experience, so go get something faster if you are building a Windows Server machine. Sure, the Windows Server hardware requirement specs say you can do it, but would you really want to? I tried this with the release candidate and reached the same conclusion, spend a few dollars more and do not go Atom with Windows Server Note, I do have a very different opinion on the viability of the Atom platform for things like Linux web servers, but for Server , get something a bit better.
I decided to put together a quick guide in terms of hardware recommendations. Unfortunately, software companies are doing per core and per CPU licensing so adding more slower cores and processors does not mean it is less expensive to do so. One of these days hopefully AMD will get competitive again, but as a note to AMD from a loyal user, you need to get back into the game.
Here are my ballpark recommendations:. Looking at this, there is a huge envelope to push one way or the other in terms of hardware. Some installations will need more or less, but the big theme here is to get hardware that matches the software you are purchasing. One example might be for a big Essentials installation, the Intel Xeon E is an interesting choice, especially as one can use more than 32GB of RAM as they are limited to with the Xeon E series, but one can just as easily go with two big CPUs.
When the system is being run on a computer with more than 16 GB of RAM, it'll need more disk space as well. The system needs it for dump files, paging, and hibernation. Also, the server you run it on needs to have plenty of available disk space.
Because it'll be the domain controller in a large domain. Before installing this system, we suggest you do a complete backup of all your configuration information for your servers. If you're considering getting a server, remember to look into the Windows Server R2 requirements we discussed. Don't forget about the basics. Your system should have a bit 1.
You can run this server on your system. Yet, remember that it will run better if you're able to get the hardware for optimum performance. Did you know that hybrid servers deliver the best performance for Windows Server R2? 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.
