1. On LON-DC1, read the contents in E:\Labfiles\Mod04\LabUsers.ps1 to identify the header requirements for the .csv file.
2. Edit the contents in E:\Labfiles\Mod04\LabUsers.csv, and then add the appropriate header.
Task 2: Prepare the script
1. On LON-DC1, use Windows PowerShell Integrated Scripting Environment (ISE) to modify the variables in LabUsers.ps1:
o $csvfile: E:\Labfiles\Mod04\labUsers.csv o $OU: "ou=LondonBranch,dc=adatum,dc=com" 2. Save the modified LabUsers.ps1.
3. Review the contents of the script.
Task 3: Run the script
1. On LON-DC1, open a Windows PowerShell command prompt, and then run
E:\Labfiles\Mod04\LabUsers.ps1.
2. At the Windows PowerShell prompt, use the following command to verify that the users were created: Get-ADUser -Filter * -SearchBase "ou=LondonBranch,dc=adatum,dc=com"
3. On LON-CL1, sign in as Luka with the password Pa$$w0rd.
Results: After completing this exercise, you will have used Windows PowerShell to create user accounts in

Exercise 3: Using Windows PowerShell to Modify User Accounts in Bulk
Scenario
You have received a request to update all user accounts in the new branch office OU with the correct address of the new building. Additionally, you have been asked to ensure that all of the new user accounts in the branch office are configured to force users to change their passwords the next time they sign in. The main tasks for this exercise are as follows:
1. Force all user accounts in LondonBranch to change their passwords at next sign in. 2. Configure the address for user accounts in LondonBranch.
Task 1: Force all user accounts in LondonBranch to change their passwords at next
sign in
1. On LON-DC1, open a Windows PowerShell Command Prompt window.
2. At the Windows PowerShell prompt, create a query for user accounts in the LondonBranch OU by using the following command:
Get-ADUser -Filter * -SearchBase "ou=LondonBranch,dc=adatum,dc=com" | Format-Wide DistinguishedName
3. At the Windows PowerShell prompt, modify the previous command to force all users to change their password the next time they sign in by using the following command:
Get-ADUser -Filter * -SearchBase "ou=LondonBranch,dc=adatum,dc=com" | Set-ADUser -ChangePasswordAtLogon $true
Task 2: Configure the address for user accounts in LondonBranch
1. On LON-DC1, open the Active Directory Administrative Center.2. Open the properties for all user accounts in LondonBranch. 3. Set the address for multiple users as follows:
o Street: Branch Office o City: London
o Country/Region: United Kingdom
Results: After completing this exercise, you will have modified user accounts in bulk.

Review Questions
Question: A colleague is creating a Windows PowerShell script that creates user accounts
from data in a .csv file. However, his script is experiencing errors when attempting to set a default password. Why might this be happening?
Question: You are an administrator for a school district that creates 20,000 new user
accounts for students each year. The administration system for students generates a list of the new students and then exports it as a .csv file. After the data is exported to a .csv file, what information do you need to work with the data in a script?
Question: The Research department in your organization has been renamed “Research and
Development.” You need to update the department property of users in the Research department to reflect this change.
You have created a query for user accounts that have the department property set to
Research, by using the Get-ADUser cmdlet and the -filter parameter. What is the next step
to update the department property to Research and Development?
