Every now and then I am facing a situation where some old DSC Node remains on the registration list in the Azure Automation DSC pull server.

The nodes appear for a brief moment (1-2 seconds) after clicking on the DSC Nodes menu item (or tile) and disappear. I cannot access them otherwise. The number of DSC Nodes also includes those registrations.

The virtual machine on the screenshots does not exist anymore, adding a new one with the same name and in the same Resource Group creates a new registration entry.

How can I remove the old registrations (other than deleting and recreating the Automation Account)?


In PowerShell, locate the DSC Node registration with:

PS C:\> Get-AzureRmAutomationDscNode `
            -ResourceGroupName $resourceGroupName `
            -AutomationAccountName $automationAccountName

Get the Id parameter (GUID) and unregister with:

PS C:\> Unregister-AzureRmAutomationDscNode `
            -ResourceGroupName $resourceGroupName `
            -AutomationAccountName $automationAccountName `
            -Id xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
