Unable to join a Server to our Legacy Domain

I'm attempting to add a VM in Azure to our legacy AD (running on Server 2012 R2). We have a point-to-point VPN between Azure and our environment. All ports are open. All firewalls are off. I am able to ping the legacy domain. I get a prompt for credentials when attempting to add the computer, but the effort ends with the following error message: "The network location cannot be reached." I have done the following:

  1. Unchecked and rechecked Client Microsoft Networks.
  2. Ran ipconfig /flushdns
  3. Ran ipconfig /registerdns
  4. Ran netsh winsock reset

Any help would be appreciated.

    I'd check the domain controller and problem member both have the static ip address of DC listed for DNS and no others such as router or public DNS. Also check that the required ports are open and flowing between networks.
