Forcibly removing Azure Arc on-prem server from Defender for Cloud

Take this:

• Unregister the Server from Azure Arc:
  • Go to the Azure portal and navigate to the Azure Arc resource group where the server is listed.
  • Select the server you want to remove and click Delete. This will unregister the server from Azure Arc.
• Remove the Server from Defender for Cloud:
  • Navigate to Microsoft Defender for Cloud in the Azure portal.
  • Under the Inventory section, locate the server you want to remove.
  • Select the server and choose Delete or Remove from the options.
• Clean Up Extensions:
  • If the server was onboarded with extensions (e.g., Log Analytics agent), ensure these are removed. You can do this by navigating to the Extensions section of the server in the Azure portal and uninstalling any associated extensions.
• PowerShell or CLI:
  • If the server still appears in Defender for Cloud, you can use Azure PowerShell or CLI commands to remove it:

Remove-AzResource -ResourceId "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.HybridCompute/machines/{machineName}" -Force
