Machines should have a vulnerability assessment solution - troubleshooting

Hi Erik_Snijder,

to troubleshoot the issue that you are experiencing, you can follow these steps:

1. Check if the VM has been onboarded to Microsoft Defender for Endpoint. You can do this by running the following command on the VM:

Get-MPComputerStatus​

If the output of the command shows that the VM is running and protected, then it has been onboarded to Microsoft Defender for Endpoint. Otherwise, you will need to onboard the VM manually.

1. Check if the VM has the latest version of the Microsoft Defender for Endpoint agent installed. You can do this by running the following command on the VM:

Get-MpComputerStatus -IncludeDefenderVersion​

If the output of the command shows that the agent version is lower than 1.396.2420.0, then you will need to update the agent.

1. Check if the VM is communicating with the Microsoft Defender for Endpoint service. You can do this by running the following command on the VM:

Test-MpConnectivity​

If the output of the command shows that the VM is connected, then it is communicating with the Microsoft Defender for Endpoint service. Otherwise, you will need to troubleshoot the communication issue.

1. If the VM is onboarded to Microsoft Defender for Endpoint, has the latest version of the agent installed, and is communicating with the Microsoft Defender for Endpoint service, but still does not appear in the Microsoft 365 Defender portal, then you can try the following:

• Restart the Microsoft Defender for Endpoint service.
• Restart the VM.
• Remove and reinstall the Microsoft Defender for Endpoint agent.
