How to delete a Network Interface which is attached to a deleted VM?

Question

Hi everyone,

I'm trying to delete a network interface (NIC) from Azure, but it's complaining that the NIC as attached to a virtual machine that no longer exists in my subscription.

Steps I’ve tried:

• Deleted the VM (confirmed it’s not showing up anywhere in Azure)
• Tried deleting the NIC from the Azure Portal, the error says it’s still attached to a non-existent VM
• Tried using Azure CLI

Has anyone run into this before? How can I force-delete or detach this NIC when the VM no longer exists?

Thanks in advance

Hi Daniel Lee,

As we discussed over the teams that, we had helped you identify your orphaned NIC was attached to another deployment & you have mentioned M365 Cloud PC had a NIC in azure & you have successfully deleted the NIC now & its fixed.

We are glad that we are able to help in fixing the issue.

You will probably need to use scripting here. Can you open a CloudShell terminal and try the following AzCli (bash) commands:

az network nic show --name <NIC_NAME> --resource-group <RESOURCE_GROUP>

Check if the virtualmachine property is still set here. if so, then remove using the below command:

az network nic update \

  --name <NIC_NAME> \

  --resource-group <RESOURCE_GROUP> \

  --remove virtualMachine

Hi Daniel Lee,

Thanks for the reply, please try to use below comments to delete the NIC.

Get-AzNetworkInterface | where-object { $_.VirtualMachine -eq $null } | ft name

Get-AzNetworkInterface | where-object { $_.VirtualMachine -eq $null } | Remove-AzNetworkInterface -Force

If above steps does not work, please check with resource.azure.com.

• Open a web browser and navigate to https://resources.azure.com
• Log-in to the appropriate Azure account
• In the blade on the left side of the browser, expand subscriptions, then expand the desired subscription name
• In the blade on the left side of the browser, expand resource groups
• Under resource groups, expand the proper Resource Group Name
• Under the Resource Group, expand providers
• Under providers, expand Microsoft.Network
• Under Microsoft.Network, expand networkinterfaces
• Under networkinterfaces, select the NIC which you are failing to delete.
• Near the top of the content window of the browser, select the Read/Write push button
• Select the Actions(POST, DELETE) tab and click on Delete.
