How to monitor FSMO roles changes

Start your free trial

In Active Directory, FSMO roles define the responsibilities for each domain controller (DC) in a forest along with the domains under it. If a compromised user were to transfer the FSMO role from one DC to another, this could cause a huge security risk in the network. This newly attained authority from the FSMO role could be misused by users with admin access to that DC. This is why it's important to keep an eye on changes made to FSMO roles.

Steps to enable auditing using GPMC

In order to monitor FSMO role changes, you first need to enable auditing for these changes. To do this, perform the following actions on the DC:

  1. Go to Start > Group Policy Management Console. You can also run the command gpmc.msc with elevated privileges.

  4. Note: If you want to link the auditing policy to an existing GPO, select Link an Existing GPO...

Though Windows' native auditing allows you to look for changes in the FSMO roles, it becomes strenuous and often impossible to manually analyze and investigate changes on a large scale. In such scenarios, you need an intuitive and interactive solution that can monitor and alert you about the changes, and provide you with exhaustive reports on the change action.
