How to enable, disable, and unlock accounts in Active Directory

Introduction

This tutorial will guide you through the process of enabling, disabling, and unlocking accounts in Active Directory. Understanding these functions is essential for managing user and computer accounts effectively in a Windows Server environment.

Step 1: Enabling User and Computer Accounts

To enable users and computers in Active Directory, follow these steps:

1. Open the Active Directory Users and Computers console.
2. Locate the users or computers you wish to enable. They will have a downward-facing arrow icon indicating they are disabled.
3. Right-click on the user or computer account.
4. Select Enable Account from the context menu.
   • The downward arrow will disappear, indicating the account is now enabled.
5. To enable multiple accounts simultaneously:
   • Hold down the Shift key.
   • Click on the first account and then the last account in the selection range.
   • Right-click on the selected accounts and choose Enable Account.

Practical Tip

Avoid selecting security groups when enabling or disabling accounts, as the option will not be available for groups.

Step 2: Disabling User and Computer Accounts

To disable an account, which prevents login access to resources:

1. In the Active Directory Users and Computers console, right-click on the enabled user or computer account.
2. Select Disable Account from the menu.
   • This action will prevent the user or computer from logging into Active Directory.

Common Pitfall

Remember that when an account is disabled, the user or computer cannot access any network resources. Ensure you only disable accounts when necessary.

Step 3: Managing Account Expiration

To set an expiration date for a user account:

1. Double-click on the user account to open its properties.
2. Navigate to the Account tab.
3. Check the box for Account expires.
4. Select the expiration date using the calendar tool.
5. Click Apply to save your changes.

Step 4: Unlocking User Accounts

If a user account is locked due to too many failed login attempts:

1. In the Active Directory Users and Computers console, locate the locked user account.
2. Right-click on the account and select Unlock Account.
3. Click Apply to enable the user to log in again.

Explanation

A locked account is not the same as a disabled account. A lock occurs when login attempts exceed the allowed limit as defined by group policy.
