How to Track who disabled a user in Active Directory

Active Directory configuration changes need to be carefully monitored so that users have access to all the resources they require. If a user’s account becomes disabled, they will not have access to essential system functions including email, files and SharePoint which will disrupt business operations.

Another reason to ensure that disabled users are tracked in Active Directory is to reduce the risk of a data breach. Disabled accounts represent a serious threat as they can be re-enabled and misused by attackers seeking access to Active Directory, Windows servers and other AD-integrated systems. Therefore, it is crucial to have visibility over who disabled a user account to establish the reason for doing this.

In this article, we will discuss the steps you need to take to detect who disabled a user account in Active Directory. We will first look at doing this using native auditing, followed by a more straightforward approach using the Lepide Auditor for Active Directory.
