Unable to delete the subnet in Azure

My resource group is in centralUS and I created a VM in Japan East. In the resource group, I selected all the resources and deleted but few resources like Disk, NIC, NSG, VNET are not been deleted. Getting the below error messages

Error messges;

Error: Subnet pointersubnet is in use by River-Dale/providers/Microsoft.Network/networkInterfaces/desktop729/ipConfigurations/ipconfig1'>desktop729/ipconfig1 and cannot be deleted. In order to delete the subnet, delete all the resources within the subnet. See aka.ms/deletesubnet.

Answer 1

I reached out to support request and they asked me to execute the cmd I executed the cmd

Remove-AzResourceGroup -Name [NAME OF RESOURCEGROUP] –Force

But I received the error as below several times

Remove-AzResourceGroup -Name River-Dale -ForceRemove-AzResourceGroup: Long running operation failed with status 'Conflict'.
StatusCode: 409
ReasonPhrase: Conflict
OperationID :

Post which I performed the below actions and then executed the cmd Remove-AzResourceGroup -Name [NAME OF RESOURCEGROUP] –Force and then it worked!!!! my resource group River-Dale got deleted.

1. Created VM with the same name & region as the deleted one
2. Associated the VNET (which I am unable to delete) to the created VM

After that, I executed the cmd and it deleted my resource group

Hello @Deepak sundaram ,

Please try the below provided steps:

Open a web browser and navigate to https://resources.azure.com

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.
Once this NIC is deleted, you can retry to delete the ResourceGroup.
If it does not succeed and you receive an error, please share the error for further investigation.

Also, what output do you get when you run the below cmdlet:
Get-AzVm -Name "Desktop" -ResourceGroupName "River-Dale"

Alternatively, you may use the Azure PowerShell/CLI commands to remove the ResourceGroup. Please refer : https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/delete-resource-group?tabs=azure-powershell#delete-resource-group
