Creating and Using Group Policy
Complete Guide to Creating and Using Group Policy

Step 1: Understanding Group Policy

Think of Group Policy as Windows Server’s handy assistant. It helps administrators shape the work environment of both users and computers across the network. In an Active Directory environment, Group Policy plays a key role, offering centralized management and configuration.

Group Policies collect user and computer configuration settings. You can link these collections to computers, sites, domains, and Organizational Units (OUs) in an Active Directory.

Group Policy consists of two main components:

Group Policy Objects (GPOs): GPOs collect policy settings and offer a unique scope of management. They reside on the domain controller, and client systems within the domain can download and process them.

Group Policy Settings: These individual settings reside within a GPO. Each setting defines a user or computer system configuration’s state and can be either enabled, disabled, or not configured.

The functions that Group Policy settings can manage are vast, including:

Software Installation and Maintenance: Network administrators can use GPOs to deploy, update, or uninstall software applications network-wide.

Security Settings: Network administrators have the ability to define password policies, account lockout policies, audit policies, and more.

User and System Environment: An administrator can leverage GPOs to configure desktop settings, start menu layout, and scripts for startup or shutdown.

Understanding the pivotal role and capabilities of Group Policy forms the basis of effective Windows Server management. It empowers the administrator to establish rules and policies, ensuring all networked computers meet organizational standards and security protocols.

Step 2: Accessing Group Policy Management

Group Policy Management is the tool that enables you to create, modify, or remove Group Policies in your Windows Server environment. This Microsoft Management Console (MMC) snap-in provides an all-in-one solution for managing all Group Policy tasks.

To start, you need to ensure Group Policy Management is installed on your Windows Server. It’s usually pre-installed with the server. If you find it missing, add it through your Server Manager Dashboard. You can do this by navigating to “Manage,” selecting “Add Roles and Features,” and finally choosing “Group Policy Management” from the features list.

Once you’ve installed Group Policy Management, follow these steps to access it:

Open Server Manager: This central console lets you manage your server roles and features. It’s usually the first screen you see when logging into your Windows Server.

Access Tools Menu: Find the “Tools” menu in the upper right corner of the Server Manager Dashboard and click on it to see a dropdown list of management tools.

Select Group Policy Management: From the list of tools, locate “Group Policy Management” and click on it. This will open the Group Policy Management Console (GPMC).

Inside the GPMC, you will see your forest, domains, and Group Policy Objects (GPOs). Here, you can create new GPOs, alter existing ones, and set their scope of management. Link these GPOs to an Organizational Unit (OU), a domain, or a site to apply the policy settings to all computers and users within those scopes.

Mastering the navigation of the Group Policy Management Console is a key step in leveraging Group Policy in your Windows Server environment. This central hub is where you’ll carry out most of your Group Policy tasks.

 

 

Step 3: Creating a New Group Policy Object (GPO)

Let’s delve into creating a new Group Policy Object (GPO) using the Group Policy Management Console (GPMC).

Think of GPOs as the specific rules you establish for your network. They contain various settings that you plan to implement, and you can link each GPO to one or multiple Active Directory objects such as sites, domains, or Organizational Units (OUs).

Follow these steps to create a new GPO:

Launch the Group Policy Management Console: You can do this via the ‘Tools’ menu in your ‘Server Manager’ dashboard.

Navigate to Group Policy Objects: Once inside the GPMC, expand the ‘Forest’ and ‘Domains’ folders in the left panel. Then, click on the specific domain where you want to create the GPO. You will find the ‘Group Policy Objects’ folder right under the domain.

Create a New GPO: Select ‘New’ from the dropdown menu that appears when you right-click on the ‘Group Policy Objects’ folder. A ‘New GPO’ dialog box will pop up.

Name Your GPO: The ‘New GPO’ dialog box will prompt you to name your new GPO. Ensure you choose a meaningful name that reflects its purpose, which will make management easier in the future. After naming your GPO, click ‘OK’.

You’ve now created a new GPO and it’s ready for configuration. Keep in mind, when you create a new GPO, it initially contains no configured settings and won’t affect any users or computers. It only begins to take effect after you link it to an Active Directory object (like a domain, an OU, or a site) and configure its settings.

Creating GPOs offers a centralized way to manage and configure your network. It eases your workload and ensures consistency across your network.

Step 4: Configuring Your GPO

Once you’ve created a Group Policy Object (GPO), you will need to configure it with the policy settings you want to enforce or implement across your network. Each GPO contains two main sections: User Configuration and Computer Configuration. Each section further includes three sub-sections: Policies, Preferences, and Settings.

Here’s a step-by-step guide on how to configure your newly created GPO:

  1. Navigate to the GPO: First, open the Group Policy Management Console (GPMC) through the ‘Server Manager’ dashboard. Navigate to the ‘Group Policy Objects’ folder under the domain where your GPO was created.
  2. Edit the GPO: Right-click on the GPO you want to configure and select ‘Edit’. This will open the Group Policy Management Editor window, where you can configure the policy settings for the GPO.
  3. Explore the GPO Settings: In the Group Policy Management Editor, you’ll see a hierarchical structure of folders under both ‘Computer Configuration’ and ‘User Configuration’. These folders contain hundreds of potential settings that you can configure based on your organization’s needs.
  4. Configure Policy Settings: To configure a setting, navigate to it, right-click on it and select ‘Edit’. For instance, if you want to set a password policy, you would navigate to Computer Configuration > Policies > Windows Settings > Security Settings > Account Policies > Password Policy. Then, select the policy you want to edit, such as ‘Maximum password age’ or ‘Password must meet complexity requirements’. A dialog box will open where you can configure the desired setting.
  5. Save Your Configurations: After setting up your desired configurations, make sure to save your changes. Most changes are saved automatically, but it’s always a good idea to confirm.

Note: The GPO settings you configure will depend heavily on the requirements of your specific network or organization. Be sure to understand each policy setting before you enable, disable, or modify it.

The capability to define multiple policies and apply them selectively across the network is what makes the Group Policy feature so powerful. Once you’ve configured your GPO, the next step is to link it to the respective Organizational Unit (OU), domain, or site where it will be applied.

Step 5: Applying GPO

Linking or applying a Group Policy Object (GPO) enables you to enforce the rules and configurations you’ve set up on groups of users or computers within your network. You can link GPOs to three types of Active Directory (AD) containers: Sites, Domains, and Organizational Units (OUs).

To apply your newly configured GPO, follow these steps:

Navigate to the Target AD Container: Access the Group Policy Management Console (GPMC) from your ‘Server Manager’ dashboard. Then, locate the AD container (site, domain, or OU) where you want your GPO to apply in the left-hand pane.

Link the GPO: Select ‘Link an Existing GPO’ from the dropdown menu that appears when you right-click on the target AD container. A dialog box containing a list of all available GPOs in your domain will then appear.

Select Your GPO: Find and choose the GPO you recently created and configured in the dialog box. Then, click ‘OK’.

Now, your GPO links to your chosen AD container, and the GPO’s configured settings will apply to all computers and users within this container.

Remember, GPOs process in this order: Local, Site, Domain, and OU. If multiple GPOs linked to the same AD container have conflicting settings, the last processed GPO will take precedence.

It’s also worth noting that GPOs linked to OUs only apply to the users or computers within that OU. To apply a GPO across the entire domain, you need to link it at the domain level.

Linking or applying your GPO is a vital step in using Group Policy for network management. This process allows you to enforce your configurations and manage your network more efficiently.

Step 6: Testing Your GPO

After you have created, configured, and linked your Group Policy Object (GPO), it’s crucial to verify that it’s functioning as expected. Testing your GPO helps ensure your settings have been applied correctly and are exerting the desired effect.

Here’s how to test your GPO:

  1. Select a Test Computer or User: Choose a computer or user that falls within the scope of the GPO you’ve created. Ideally, this should be a test user or machine that mimics the settings of your target audience but doesn’t disrupt productivity if something goes wrong.
  2. Force a Group Policy Update: On the selected test machine, you can manually force a Group Policy update to make the changes take effect immediately. To do this, open the Command Prompt and enter the following command: gpupdate /force. This command forces an immediate update of all Group Policies.
  3. Verify the Applied Policies: After running the update, you can check if the new policies have been applied successfully. You can use the Resultant Set of Policy (RSoP) tool for this. In the Command Prompt, type rsop.msc to open the RSoP tool, which shows the cumulative effect of all applied Group Policies.
  4. Check the Specific Setting: Navigate to the setting you have configured in the GPO. If the GPO has been applied successfully, you should see the updated setting.
  5. Troubleshoot If Necessary: If the GPO is not applied as expected, you might need to troubleshoot. Check the Group Policy application order, security filtering, GPO status, and WMI filters, among other things.

Testing and verifying your GPOs are critical steps in the Group Policy management process. These ensure your configurations are working as intended and allow you to troubleshoot any issues that might arise before they affect your entire network. Remember, making changes in Group Policy can have widespread effects, so it’s always best to test thoroughly to avoid any unintended consequences.
