Note: You can use the search feature at the top of the window to find the group. You will also need to uncheck Protect from accidental deletion from within the group properties. e. Delete the Redmond organizational unit. f. In the Confirm Subtree Deletion dialog box, check Use delete subtree server control and then click Yes. Note: In this task you will use Windows PowerShell to query the contents of the Active Directory Recycle Bin. Objects that have been deleted are moved to this location and have their distinguished name adjusted to reflect the fact that they are a deleted object, and also to avoid conflicts when multiple objects of the same common name are deleted. a. On the Start menu, point to Administrative Tools and then click Active Directory Module for Windows PowerShell. b. To display the contents of the Recycle Bin, in Windows PowerShell, type the following command and then press ENTER: Get-ADObject SearchBase CN=Deleted Objects,DC=Woodgrovebank,DC=Com ldapfilter (objectclass=*) -includedeletedobjects Note: This command displays the entire contents of the Recycle Bin. Leave the output of this command on the screen as you will use it in the next task. c. To verify the Alice Ciccu user object is in the Recycle Bin, in Windows PowerShell, type the following command and then press ENTER: Get-ADObject Filter {Name Like *Alice Ciccu* } SearchScope Subtree includedeletedobjects Format-List Note: The output of this command will show the details for the Alice Ciccu user object. Note the distinguished name indicates this object is in the AD Recycle Bin. d. In Windows PowerShell, type the following command and then press ENTER: Get-ADObject Filter {Name Like *Redmond* } SearchScope Subtree IncludeDeletedObjects Format-List Note: The output of this command will show the details for the RedmondSupport user group as well as the Redmond OU. Note the distinguished name indicates this object is in the AD Recycle Bin. Note: In this task you will use the Recover-ADObject PowerShell Cmdlet to recover objects that have been deleted from Active Directory. Ensure Active Directory Module for Windows PowerShell is open. a. In Windows PowerShell, copy the objectguid value for the object Alice Ciccu to the clipboard. Note: To copy text from a command prompt, right click and then select Mark. Highlight the text to copy and then press ENTER. To paste, right click and then click Paste. b. To attempt to restore the Alice Ciccu user account, in Windows PowerShell, type the following command and then press ENTER: Note: To complete the following command, copy the value of the objectguid property from the Alice Ciccu object. Restore-ADObject Identity <objectguid> Page 9 of 12

12 Note: The command fails with an error message indicating that the object s parent object does not exist. You can then query for the last known parent of the object and restore that object. c. To identify the last known parent of Alice Ciccu, in Windows PowerShell, type the following command and then press ENTER: Note: To save typing, use the up arrow key to locate the previous search command and append the additional parameters to it. Get-ADObject Filter Name Like *Alice Ciccu* SearchScope Subtree includedeletedobjects properties lastknownparent Format-List Note: This command displays the last known parent object, which, you can tell, is also in the Recycle Bin. d. To restore the OU which contains Alice Ciccu, in Windows PowerShell, type the following command and then press ENTER: Note: To complete the following command, copy the value of the objectguid property from the Redmond object which can be found from the output of the last command in Step 3 in the Verify Objects are Now in the Recycle Bin exercise. Restore-ADObject Identity <objectguid> e. To restore the Redmond OU Objects, including Alice Ciccu, in Windows PowerShell, type the following command and then press ENTER: Get-ADObject ldapfilter (lastknownparent=ou=redmond,ou=king,ou=washington,ou=america,dc=woodgr ovebank,dc=com) includedeletedobjects Restore-ADObject Note: This command lists all objects that have the last known parent attribute as the Redmond OU and pipes them into the Restore-ADObject Cmdlet. 5. Verify that Deleted Objects have been Recovered Note: In this task you will review Active Directory to ensure that the deleted objects have been recovered. a. If not open, on the Start Menu, point to Administrative Tools and then click Active Directory Administrative Center. Note: Ensure you refresh your view in Active Directory Administrative Center after you make changes to ensure you see those changes. b. Navigate to the America\Washington\King OU. c.

13 Exercise 4 Pre-Deploying Computer Accounts using Offline Domain Join Scenario In this exercise you will complete the tasks required to provision an account for offline domain join. Offline domain join involves two steps. In the first step you will provision a computer account in Active Directory and save the account information in a file. In the second step you will use that file in a command that inserts the domain join information into an offline version of Windows. Complete the following task on: BAL-DC Provision a Computer Account for Offline Domain Join Note: In this task you will use the DJoin command to provision a computer account in Active Directory for offline domain join. The result of this task is a file that can be merged into an offline copy of Windows, ensuring that the first time the computer starts it is domain joined. a. On the Start menu, click Command Prompt. b. To provision a new computer account, in the Command Prompt, type the following command and then press ENTER: DJOIN /Provision /Domain Woodgrovebank.com /Machine BAL-SRV-10 /SaveFile BAL- SRV-10.DJoin Note: This command creates a computer account in Active Directory and stores the computer account password and related information in an encrypted file. The encrypted file can then be used to offline domain join a computer. c. To display the contents of the provisioning file, in the Command Prompt, type the following command and then press ENTER: Type BAL-SRV-10.DJoin Note: The contents of the.djoin file are encrypted. 2. Verify the Computer Account has been Created in Active Directory Note: In this task you will look at Active Directory to verify that the offline domain join has correctly created the computer account for BAL-SVR-10. a. On the Start menu, point to Administrative Tools and then click Active Directory Administrative Center. b. Navigate to Woodgrovebank (local)\computers. Note: Note that the computer account BAL-SRV-10 has been created. 3. Review the Process to Perform an Offline Domain Join Note: In this task you will type the command used to perform an offline domain join operation. This command will use the contents of the saved file created in the previous task to insert domain join information into the computer s registry without having to start the operating system. This command can be run on an offline copy of Windows such as a WIM file or VHD which has been mounted. Begin this task with a command prompt window open. a. To perform an offline domain join, use the following command: Page 11 of 12
