title: How can I deploy an Azure virtual machine scale set to an existing virtual network?
body: <p>I have successfully deployed a VMSS with an AD server in the same VLAN.  However, when I try to deploy a second VMSS it create a new virtual network, placing it away from my existing AD.</p>
  
  <p>How do I deploy the second VMSS into the same virtual network as the first and AD?  If I edit a template to have the same virtual network as the existing one, then deploy it, will the deployment be into the existing virtual network or will it attempt to create a new one with the same name and fail or duplicate it?</p>
  
  <p>Alternatively, is there any way to migrate the NIC in a VMSS to another network?  I can't find a cmdlet to do it and in the web interface it only shows the virtual network created at deployment in the drop-down and not the original virtual network.</p>
