On June 9, 2026, Microsoft released KB updates that conflict with the Active Directory (AD) Module in the Netwrix Activity Monitor product.
If these KBs are applied before updating the AD Module, certain Kerberos Authentication and LDAP Bind events will no longer be captured.
Netwrix recommends delaying deployment of these KBs if your organization relies on these event types. The Netwrix development and QA teams are working on an updated AD Module compatible with these KBs and will send another notice when it is available.
Important Details
If your organization does not use Netwrix Activity Monitor for the following Active Directory activity event collection, or such events are not deemed important, you may elect to deploy the following Microsoft KBs in advance of the updated AD Module.
No other aspect of Activity Monitor operation is impacted by the June 9, 2026 KBs beyond what is described below. There is no adverse impact to domain controllers if the KBs are deployed without updating the AD Module.
