Lab answer key: Implementing identity services and Group Policy

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.

Exercise 1: Deploying a new domain controller on Server Core

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

  1. Connect to SEA-ADM1 and, if needed, sign in as CONTOSO\Administrator with a password of Pa55w.rd.
  2. On SEA-ADM1, select Start, and then select Windows PowerShell (Admin).
  3. To install the AD DS server role, at the Windows PowerShell command prompt, enter the following command, and then press Enter:
    Code
    Install-WindowsFeature –Name AD-Domain-Services –ComputerName SEA-SVR1
    
  4. To verify that the AD DS role is installed on SEA-SVR1, enter the following command, and then press Enter:
    Code
    Get-WindowsFeature –ComputerName SEA-SVR1
    
  5. In the output of the previous command, search for the Active Directory Domain Services checkbox, and then verify that it is selected. Then, search for Remote Server Administration Tools. Notice the Role Administration Tools node below it, and then verify that the AD DS and AD LDS Tools node is also selected.

    Note: Under the AD DS and AD LDS Tools node, only Active Directory module for Windows PowerShell has been installed and not the graphical tools, such as the Active Directory Administrative Center. If you centrally manage your servers, you will not usually need these on each server. If you want to install them, you must specify the AD DS tools by running the Add-WindowsFeature cmdlet with the RSAT-ADDS command.

    Note: You might need to wait a brief time after the installation process is complete 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, on the Start menu, select Server Manager, and then, in Server Manager, select the All Servers view.
  2. On the Manage menu, select Add Servers.
  3. In the Add Servers dialog box, maintain the default settings, and then select Find Now.
  4. In the Active Directory list of servers, select SEA-SVR1, select the arrow to add it to the Selected list, and then select OK.
  5. On SEA-ADM1, ensure that the installation of the AD DS role on SEA-SRV1 is complete and that the server was added to Server Manager. Then select the Notifications flag symbol.
  6. Note the post-deployment configuration of SEA-SVR1, and then select the Promote this server to a domain controller link.
  7. In the Active Directory Domain Services Configuration Wizard, on the Deployment Configuration page, under Select the deployment operation, verify that Add a domain controller to an existing domain is selected.
  8. Ensure that the Contoso.com domain is specified, and then in the Supply the credentials to perform this operation section, select Change.
  9. In the Credentials for deployment operation dialog box, in the User name box, enter CONTOSO\Administrator, and then in the Password box, enter Pa55w.rd.
  10. Select OK, and then select Next.
  11. On the Domain Controller Options page, ensure that the Domain Name System (DNS) server and Global Catalog (GC) checkboxes are selected. Ensure that the Read-only domain controller (RODC) checkbox is cleared.
  12. In the Type the Directory Services Restore Mode (DSRM) password section, enter and confirm the password Pa55w.rd, and then select Next.
  13. On the DNS Options page, select Next.
  14. On the Additional Options page, select Next.
  15. On the Paths page, keep the default path settings for the Database folder, Log files folder, and SYSVOL folder, and then select Next.
  16. To open the generated Windows PowerShell script, on the Review Options page, select View script.
  17. In Notepad, edit the generated Windows PowerShell script:
    • Delete the comment lines that begin with the number sign (#).
    • Remove the Import-Module line.
    • Remove the grave accents (`) at the end of each line.
    • Remove the line breaks.
  18. Now the Install-ADDSDomainController command and all the parameters are on one line. Place the cursor in front of the line, and then, on the Edit menu, select Select All to select the whole line. On the menu, select Edit, and then select Copy.
  19. When prompted for confirmation, select Yes to cancel the wizard.
  20. At the Windows PowerShell command prompt, enter the following command:
    Code
    Invoke-Command –ComputerName SEA-SVR1 { }
    
  21. Place the cursor between the braces ({ }), and then paste the content of the copied script line from the clipboard. The complete command should have the following format:
    Code
    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}
    
  22. To invoke the command, press Enter.
  23. In the Windows PowerShell Credential Request dialog box, enter CONTOSO\Administrator in the User name box, enter Pa55w.rd in the Password box, and then select OK.
  24. When prompted for the password, in the SafeModeAdministratorPassword text box, enter Pa55w.rd, and then press Enter.
  25. When prompted for confirmation, in the Confirm SafeModeAdministratorPassword text box, enter Pa55w.rd, and then press Enter.
  26. Wait until the command runs and the Status Success message is returned. The SEA-SVR1 virtual machine restarts.
  27. Close Notepad without saving the file.
  28. After SEA-SVR1 restarts, on SEA-ADM1, switch to Server Manager, and on the left side, select the AD DS node. Note that SEA-SVR1 has been added as a server and that the warning notification has disappeared.

    Note: You might have to select Refresh.

Task 3: Manage objects in AD DS

  1. Ensure that you are connected to the console session of SEA-ADM1.
  2. Switch to Windows PowerShell (Admin).
  3. To create an Organizational Unit (OU) called Seattle in the Contoso AD DS domain, enter the following command, and then press Enter:
    Code
    New-ADOrganizationalUnit -Name "Seattle" -Path "DC=contoso,DC=com" -ProtectedFromAccidentalDeletion $true -Server SEA-DC1.contoso.com
    
  4. To create a user account for Ty Carlson in the Seattle OU, enter the following command, and then press Enter:
    Code
    New-ADUser -Name Ty -DisplayName 'Ty Carlson' -GivenName Ty -Surname Carlson -Path 'OU=Seattle,DC=contoso,DC=com'
    
  5. To set the password for the Ty’s user account, enter the following command, and then press Enter:
    Code
    Set-ADAccountPassword Ty
    
  6. When you receive a prompt for the current password, press Enter.
  7. When you receive a prompt for the desired password, enter Pa55w.rd, and then press Enter.
  8. When you receive a prompt to repeat the password, enter Pa55w.rd, and then press Enter.
  9. To enable the account, enter the following command, and then press Enter:
    Code
    Enable-ADAccount Ty
    
  10. To create a domain global group named SeattleBranchUsers, enter the following command, and then press Enter:
    Code
    New-ADGroup SeattleBranchUsers -Path 'OU=Seattle,DC=contoso,DC=com' -GroupScope Global -GroupCategory Security
    
  11. To add the Ty user account to the newly created group, enter the following command, and then press Enter:
    Code
    Add-ADGroupMember -Identity SeattleBranchUsers -Members Ty
    
  12. To confirm that the user is in the group, enter the following command, and then press Enter:
    Code
    Get-ADGroupMember -Identity SeattleBranchUsers
    
  13. To add the user to the local Administrators group, enter the following command, and then press Enter:
    Code
    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.
