Setting up a SharePoint Server 2016 farm in Azure?

Hi Joe Davies

I'm having issues with this code. I had to change StandardLRS to Standard_LRS to stop it crashing out and then on the final step it says "New-AzureRMVM : Object reference not set to an instance of an object." and doesn't create the VM. Please can you advise?
