Lab: Implementing identity services and Group Policy

Scenario

You are working as an administrator at Contoso Ltd. The company is expanding its business with several new locations. The Active Directory Domain Services (AD DS) Administration team is currently evaluating methods available in Windows Server for a non-interactive, remote domain controller deployment. The team is also searching for a way to automate certain AD DS administrative tasks. Additionally, the team wants to establish configuration management based on Group Policy Objects (GPO).

Note: An interactive lab simulation is available that allows you to click through this lab at your own pace. You may find slight differences between the interactive simulation and the hosted lab, but the core concepts and ideas being demonstrated are the same.

Objectives

After completing this lab, you’ll be able to:

• Deploy a new domain controller on Server Core.
• Configure Group Policy.

Estimated time: 45 minutes

Lab setup

Virtual machines: AZ-800T00A-SEA-DC1, AZ-800T00A-ADM1, and AZ-800T00A-SEA-SVR1 must be running. Other VMs can be running, but they aren’t required for this lab.

Note: AZ-800T00A-SEA-DC1, AZ-800T00A-ADM1, and AZ-800T00A-SEA-SVR1 virtual machines are hosting the installation of SEA-DC1, SEA-SVR1, and SEA-ADM1.

1. Select SEA-ADM1.
2. Sign in using the following credentials:
   • Username: Administrator
   • Password: Pa55w.rd
   • Domain: CONTOSO

Exercise 1: Deploying a new domain controller on Server Core

Scenario

As a part of business restructuring, Contoso wants to deploy new domain controllers in remote sites with minimal engagement of IT in remote locations. You need to use DC deployment to deploy new domain controllers.

The main tasks for this exercise are as follows:

1. Deploy AD DS on a new Windows Server Core server.
2. Manage AD DS objects with GUI tools and with Windows PowerShell.

Task 1: Deploy AD DS on a new Windows Server Core server

1. Switch to SEA-ADM1 and from Server Manager, open Windows PowerShell.
2. Use the Install-WindowsFeature cmdlet in Windows PowerShell to install the AD DS role on SEA-SVR1.
3. Use the Get-WindowsFeature cmdlet to verify the installation.
4. Ensure that you select the Active Directory Domain Services, Remote Server Administration Tools, and Role Administration Tools checkboxes. For the AD DS and AD LDS Tools nodes, only the Active Directory module for Windows PowerShell should be installed, and not the graphical tools, such as the Active Directory Administrative Center.

Note: If you centrally manage your servers, you will not usually need GUI tools on each server. If you want to install them, you need to specify the AD DS tools by running the Add-WindowsFeature cmdlet with the RSAT-ADDS command.

Note: You might need to wait after the installation process completes before verifying that the AD DS role has installed. If you do not observe the expected results from the Get-WindowsFeature command, you can try again after a few minutes.

Task 2: Prepare the AD DS installation and promote a remote server

1. On SEA-ADM1, from Server Manager, on the All Servers node, add SEA-SVR1 as a managed server.
2. On SEA-ADM1, from Server Manager, configure SEA-SVR1 as an AD DS domain controller by using the following settings:
   • Type: Additional domain controller for existing domain
   • Domain: contoso.com
   • Credentials: CONTOSO\Administrator with the password Pa55w.rd
   • Directory Services Restore Mode (DSRM) password: Pa55w.rd
   • Do not remove the selections for DNS and the global catalog
3. On the Review Options page, select View Script.
4. In Notepad, edit the generated Windows PowerShell script as follows:
   • Delete the comment lines, which begin with the number sign (#).
   • Remove the Import-Module line.
   • Remove the grave accents (`) at the end of each line.
   • Remove the line breaks.
5. Now that the Install-ADDSDomainController command and all the parameters are on one line, copy the command.
6. Switch to Windows PowerShell, and then at the command prompt, enter the following command:
   CodeCopy

   Invoke-Command –ComputerName SEA-SVR1 { }
   

7. Paste the copied command between the braces ({ }) and run the resulting command to start the installation. The complete command should have the following format:
   CodeCopy

   Invoke-Command –ComputerName SEA-SVR1 {Install-ADDSDomainController -NoGlobalCatalog:$false -CreateDnsDelegation:$false -Credential (Get-Credential) -CriticalReplicationOnly:$false -DatabasePath "C:\Windows\NTDS" -DomainName "Contoso.com" -InstallDns:$true -LogPath "C:\Windows\NTDS" -NoRebootOnCompletion:$false -SiteName "Default-First-Site-Name" -SysvolPath "C:\Windows\SYSVOL" -Force:$true}
   

8. Provide the following credentials:
   • Username: CONTOSO\\Administrator
   • Password: Pa55w.rd
9. Set the SafeModeAdministratorPassword as Pa55w.rd.
10. After SEA-SVR1 restarts, on SEA-ADM1, switch to Server Manager, and then select the AD DS node. Note that SEA-SVR1 has been added as a domain controller and that the warning notification has disappeared. You might have to select Refresh.

Task 3: Manage objects in AD DS

1. On SEA-ADM1, switch to the Windows PowerShell console.
2. To create an organizational unit (OU) called Seattle, in the Windows PowerShell console, run the following command:
   CodeCopy

   New-ADOrganizationalUnit -Name "Seattle" -Path "DC=contoso,DC=com" -ProtectedFromAccidentalDeletion $true -Server SEA-DC1.contoso.com
   

3. To create a user account for Ty Carlson in the Seattle OU, run the following command:
   CodeCopy

   New-ADUser -Name Ty -DisplayName 'Ty Carlson' -GivenName Ty -Surname Carlson -Path 'OU=Seattle,DC=contoso,DC=com'
   

4. To set the user’s password to Pa55w.rd, run the following command:
   CodeCopy

   Set-ADAccountPassword Ty
   

Note: The current password is blank.

1. To enable the user account, run the following command:
   CodeCopy

   Enable-ADAccount Ty
   

2. To create a domain global group named SeattleBranchUsers, run the following command:
   CodeCopy

   New-ADGroup SeattleBranchUsers -Path 'OU=Seattle,DC=contoso,DC=com' -GroupScope Global -GroupCategory Security
   

3. To add the Ty user account to the newly created group, run the following command:
   CodeCopy

   Add-ADGroupMember -Identity SeattleBranchUsers -Members Ty
   

4. To confirm that the user is in the group, run the following command:
   CodeCopy

   Get-ADGroupMember -Identity SeattleBranchUsers
   

5. To add the user to the local Administrators group, run the following command:
   CodeCopy

   Add-LocalGroupMember -Group 'Administrators' -Member 'CONTOSO\Ty'
   

   Note: This is necessary to allow sign in with the CONTOSO\Ty user account to SEA-ADM1.

Results

After this exercise, you should have successfully created a new domain controller and managed objects in AD DS.

Exercise 2: Configuring Group Policy

Scenario

As a part of Group Policy implementation, you want to import custom administrative templates for Office apps and configure settings.

The main tasks for this exercise are as follows:

1. Create and edit GPO settings.
2. Apply and verify settings on the client computer.

Task 1: Create and edit a GPO

1. On SEA-ADM1, from Server Manager, open the Group Policy Management console.
2. Create a GPO named Contoso Standards in the Group Policy Objects container.
3. Open the Contoso Standards GPO in the Group Policy Management Editor, and then browse to User Configuration\Policies\Administrative Templates\System.
4. Enable the Prevent access to registry editing tools policy setting.
5. Browse to the User Configuration\Policies\Administrative Templates\Control Panel\Personalization folder, and then configure the Screen saver timeout policy to 600 seconds.
6. Enable the Password protect the screen saver policy setting, and then close the Group Policy Management Editor window.

Task 2: Link the GPO

• Link the Contoso Standards GPO to the contoso.com domain.

Task 3: Review the effects of the GPO’s settings

1. On SEA-ADM1, open Control Panel.
2. Use the Windows Defender Firewall interface to enable Remote Event Log Management domain traffic.
3. Sign out, and then sign in as CONTOSO\Ty with the password Pa55w.rd.
4. Attempt to change the screen saver wait time and resume settings. Verify that Group Policy blocks these actions.
5. Attempt to run Registry Editor. Verify that Group Policy blocks this action.
6. Sign out and then sign in as CONTOSO\Administrator with the password Pa55w.rd.

Task 4: Create and link the required GPOs

1. On SEA-ADM1, in the Group Policy Management console, create a new GPO named Seattle Application Override that is linked to the Seattle OU.
2. Configure the Screen saver timeout policy setting to be disabled, and then close the Group Policy Management Editor window.

Task 5: Verify the order of precedence

1. On SEA-ADM1, from Server Manager, open the Group Policy Management console.
2. In the Group Policy Management Console tree, select the Seattle OU.
3. Select the Group Policy Inheritance tab and review its content.
   

   Note: The Seattle Application Override GPO has higher precedence than the CONTOSO Standards GPO. The screen saver time-out policy setting that you just configured in the Seattle Application Override GPO is applied after the setting in the CONTOSO Standards GPO. Therefore, the new setting will overwrite the CONTOSO Standards GPO setting. Screen saver time-out will be disabled for users within the scope of the Seattle Application Override GPO.

Task 6: Configure the scope of a GPO with security filtering

1. On SEA-ADM1, in the Group Policy Management console, select the Seattle Application Override GPO. Notice that in the Security Filtering section, the GPO applies by default to all authenticated users.
2. In the Security Filtering section, first remove Authenticated Users, and then add the SeattleBranchUsers group and the SEA-ADM1 computer account.

Task 7: Verify the application of settings

1. In Group Policy Management, in the navigation pane, select Group Policy Modeling.
2. Launch the Group Policy Modeling Wizard.
3. Set the target user and computer to the CONTOSO\Ty user account and the CONTOSO\SEA-ADM1 computer, respectively.
4. Step through the remaining pages of the wizard, review the default settings without modifying them, and complete the wizard, which will generate a report containing its outcome.
5. After the report is created, in the details pane, select the Details tab, and then select show all.
6. In the report, scroll down until you locate the User Details section, and then locate the Control Panel/Personalization section. You should notice that the Screen saver timeout settings are obtained from the Seattle Application Override GPO.
7. Close the Group Policy Management console.

Results

After this exercise, you should have successfully created and configured GPOs.
