Hello Manoj Robin Jebamani G,

Thank you for posting in Microsoft Community forum.

In order to adjust the minimum password length beyond 14 characters on a Windows Server 2019 Domain Controller, you'll need to employ the "Fine-Grained Password Policies" feature. Here's a step-by-step guide on how to accomplish that:

Step 1: Open the Active Directory Administrative Center

1. Click on **Start** and type **Active Directory Administrative Center**.
2. Open it.

Step 2: Create a New Password Settings Object (PSO)

1. In the left pane, navigate to your domain.
2. Click on **Password Settings Container**.
3. In the center pane, right-click and select **New** > **Password Settings**.

Step 3: Configure the Password Settings Object

1. In the New Password Settings dialog box, enter a name for your PSO.
2. Set the **Precedence** value (lower numbers have higher precedence).
3. Configure your desired password settings, including **Minimum Password Length**.

Here, you can set it to a value greater than 14.

4. Fill in other attributes as needed (e.g., Maximum Password Age, etc.).

Step 4: Apply the PSO to Users or Groups

1. In the **Direct applies to** section, add the users or groups to which you want the policy to apply.
2. Click **OK** to save the settings.

Step 5: Verify the Changes

1. To verify that the new settings are applied, you can use the Get-ADFineGrainedPasswordPolicy cmdlet in PowerShell.
2. You may also check individual users with Get-ADUserResultantPasswordPolicy.

By following these steps, you should be able to set the minimum password length to more than 14 characters.
