Reminder: This event is NOT a security incident.
During an operational incident on May 9th, Adlumin experienced an unexpected system outage that caused some Windows agents to automatically uninstall. Uninstalled Adlumin Windows Agents require re-installation to restore monitoring and protection.
The following two updates may require additional action on your part:
- We’ve identified that the provided query may not consistently retrieve all devices with uninstalled Windows Agents; In the next 24 hours new functionality will be introduced in product for self-service. In the meantime, customers are encouraged to contact Support for assistance with getting the updated list of devices for your review.
- During reinstallation customers may have encountered errors due to the new Agents .Net 4.8+ requirement. We’ve resolved this by releasing an updated installer that no longer requires an upgrade. The universal installer can bypass the .Net 4.8 requirements. See below for link and documentation:
Reminder, if you use a GPO to deploy Adlumin the Adlumin Agent will automatically reinstall everywhere when a GPO runs its cycle.
If you use a UEM tool for automatic software installation the agent will automatically reinstall. Additionally, you should be able to monitor or push out an installation package to ensure all tenant’s agents are pushed out.
