The Challenge of Checking Password Change History
Checking the password change history on Active Directory can be challenging due to various factors. Some of the common difficulties users face include:
1. Limited built-in tools: Active Directory does not provide a native graphical user interface (GUI) or built-in tools for tracking password change history. This means that users often need to rely on command-line tools or scripts to perform this task.
2. Complex queries: Retrieving the password change history involves executing complex queries using PowerShell commands. Users without prior experience or knowledge of PowerShell may find it challenging to construct the correct queries and interpret the results.
3. Access privileges: In order to retrieve the password change history, the user executing the PowerShell commands must have the necessary access privileges. Without the appropriate permissions, the user may encounter errors or be unable to retrieve the required information.
Despite these challenges, with the right knowledge and guidance, you can overcome these obstacles and successfully check the password change history on Active Directory using PowerShell. Let’s dive into the methods and steps you need to follow.
Things You Should Prepare for
Before we delve into the methods, let’s take a moment to discuss the prerequisites and things you should prepare to check the password change history on Active Directory using PowerShell:
1. Administrative access: You must have administrative access to the Active Directory domain controller or a server with the necessary permissions to execute PowerShell commands related to retrieving password change history.
2. PowerShell: Ensure that you have PowerShell installed on your system. PowerShell is a task automation and configuration framework from Microsoft that allows administrators to perform administrative tasks, including managing Active Directory.
3. Active Directory Module for PowerShell: Install the Active Directory module for PowerShell. The module enables administrators to perform various administrative tasks related to Active Directory, including retrieving password change history.
Now that you have the necessary prerequisites in place, let’s explore the methods you can use to check the password change history on Active Directory.
Method 1: Using Get-ADUser
Checking the password change history using the Get-ADUser cmdlet in PowerShell is one of the most straightforward methods. Follow the steps below to retrieve the password change history:
Step 1: Open PowerShell: Launch PowerShell with administrative privileges.
Step 2: Import the Active Directory module: Run the following command to import the Active Directory module:
"`
Import-Module ActiveDirectory
"`
Step 3: Retrieve the password change history: Execute the following command to retrieve the password change history for a specific user:
"`
Get-ADUser -Identity
"`
Replace `
Pros:
– Simple and straightforward method.
– Provides the password change history for a specific user.
Cons:
– Limited to retrieving the password change history for a single user.
– Requires administrative access and the Active Directory module for PowerShell.
Method 2: Using Event Viewer
Event Viewer is a built-in Windows tool that records various system events, including password changes. Although it is not specifically designed for retrieving password change history, you can still utilize it to gather some relevant information. Here’s how you can use Event Viewer to check the password change history:
Step 1: Open Event Viewer: Press the Windows key + R to open the Run dialog box. Type "eventvwr.msc" and press Enter.
Step 2: Locate Security events: In the left pane of the Event Viewer window, expand "Windows Logs" and click on "Security."
Step 3: Filter events: In the Actions pane on the right side, click on "Filter Current Log." In the Filter Current Log dialog box, check the "Event sources" box and select "Microsoft Windows security auditing." Click "OK" to apply the filter.
Step 4: Find password change events: Look for events with the Event ID 4723 (User Account Changes) or 4724 (User Account Management). These events indicate a password change.
Step 5: View event details: Double-click on a relevant event to view its details, including the user account, date, and time of the password change.
Pros:
– Utilizes a built-in Windows tool.
– Can provide additional contextual information along with the password change history.
Cons:
– Not specifically designed for retrieving password change history.
– Requires manual filtering and searching through event logs.
– Limited to providing information about the events rather than detailed password change history.
Method 3: Via Netwrix Auditor for Active Directory
Netwrix Auditor for Active Directory is a comprehensive solution for auditing and monitoring Active Directory. It provides a straightforward and intuitive interface to track changes, including password changes, in real-time. Here’s how you can use Netwrix Auditor for Active Directory to check the password change history:
Step 1: Install and launch Netwrix Auditor for Active Directory: Download and install Netwrix Auditor for Active Directory on a computer with administrative access to the Active Directory.
Step 2: Configure auditing settings: Follow the on-screen instructions to configure the auditing settings based on your requirements. Ensure that the password change events are included in the auditing scope.
Step 3: View password change history: Access the Netwrix Auditor for Active Directory dashboard and navigate to the password change history section. Here, you can view a comprehensive log of all password changes, including details such as the user account, date, time, and system from which the change was made.
Pros:
– User-friendly interface with a dedicated section for password change history.
– Real-time monitoring and alerts for password changes.
– Provides detailed information about password changes, including user accounts, dates, times, and sources.
Cons:

– May involve additional costs for purchasing and licensing Netwrix Auditor for Active Directory.
Method 4: Using PowerShell Scripts
If you prefer a more customized approach and have a good understanding of PowerShell scripting, you can create your own PowerShell script to retrieve the password change history. Here’s an example of a script you can use:
Step 1: Open a text editor: Open a text editor such as Notepad.
Step 2: Write the PowerShell script: Copy and paste the following script into the text editor:
"`
$Domain = "yourdomain.com"
$User = "username"
$DC = Get-ADDomainController -DomainName $Domain
$Logs = Get-WinEvent -ComputerName $DC -FilterHashtable @{LogName=’Security’; ID=4724} |
?{$_.Properties[1].Value -eq $User} |
Select-Object -Property @{Name="Time"; Expression={$_.TimeCreated}},
@{Name="EventID"; Expression={$_.ID}},
@{Name="User"; Expression={$_.Properties[1].Value}}
$Logs
"`
Replace "yourdomain.com" with your actual domain name and "username" with the username for which you want to check the password change history.
Step 3: Save the script: Save the file with a .ps1 extension, such as "password_change_history.ps1".
Step 4: Run the script: Open PowerShell with administrative privileges, navigate to the directory where you saved the script, and execute the following command:
"`
.\password_change_history.ps1
"`
Pros:
– Provides flexibility to customize the script according to specific requirements.
– Allows automation and scheduling of password change history checks.
Cons:
– Requires scripting and PowerShell knowledge.
– May require additional troubleshooting and debugging.
Why Can’t I Check Password Change History?
1. Restricted access: If you do not have administrative access or the necessary permissions, you may be unable to check the password change history on Active Directory. Ensure that you have the appropriate access privileges before attempting to retrieve this information.
2. Lack of PowerShell knowledge: Active Directory password change history can only be checked through PowerShell commands or scripts. If you are not familiar with PowerShell, it can be challenging to construct the correct queries or scripts to retrieve the required information. Consider familiarizing yourself with PowerShell or seeking assistance from someone with PowerShell expertise.
3. Limited tools and interfaces: Active Directory does not provide a native GUI or user-friendly interface to check the password change history. This lack of built-in tools may make it more challenging for users who are accustomed to graphical interfaces to perform this task.
Fixes:
– Ensure that you have administrative access or the necessary permissions.
– Invest time in learning PowerShell or seek assistance from someone with PowerShell expertise.
– Explore alternative methods and tools, such as third-party software or scripts, to overcome the limitations of native Active Directory functions.
Additional Tips
