Virtual Machine onboarding problem to vulnerability assessment

Question

I have enabled Microsoft Defender as a vulnerability assessment tool for all my VMs within a subscription. Three of them show up in Advisor with title: "Machines should have a vulnerability assessment solution" and details: "Virtual Machine onboarding problem to vulnerability assessment. Make sure it’s properly onboarded to Microsoft Defender for Endpoint.". I tried fixing them via Azure portal, as well as uninstalling and installing them. In the Extensions + VM Applications tam on Azure portal all Extensions have status: Provisioning succeeded. Any tips how to solve this problem? Out of about 50 VMs, only three encountered this problem.

Hope you followed the suggestion posted by deherman-MSFT, i.e, waiting for 24 hours after enabling the vulnerability solution:

• If that did not work, try and validate if there are any pending updates on the dependency's extension, kindly try updating them.

• Also validate if "defender for servers" service is running on the impacted VM, like in my case I have defender for SQL so respective service must be running:

• If you don't see the service, then validate if the VM have the following folder or not in C:/Packages/Plugins/ with name similar to Microsoft.Azure.AzureDefenderForServer

If folder is not found try to copy it from any working VM on this location, restart the VM and try running the service.
