I have a domain controller set up in an Azure VM, and a couple of other servers also set up as VMs. When I set up the server VMs, I configured DNS and WINS to point to the IP address of the DC and joined them to the domain. However, these settings don't survive a shutdown (where the VM is deallocated). When the VM is started back up, DNS and WINS are empty, and domain authentication does not work.
I read that I should provision new VMs via PowerShell commandlets, specifically setting up domain joining. I tried that, and maybe I got something wrong, but it didn't work -- the newly provisioned VM was not joined to the domain, and did not have DNS/WINS set to point to the domain controller.
In any event, my question is: is there any way to re-configure an existing VM to retain network settings through a shutdown or is my only option to figure out how to provision a brand new VM to be married to the domain controller, and then to start from scratch?
Thanks!
