Naming the process, not the technology
I have found that many people who use a VPN don't understand its relationship to RDC and meld the two in their mind. In fact, when I ask the ones I support, "Do you use Remote Desktop Connection after you establish the VPN?" most of them have no idea how to answer. But you are right that the underlying connectivity is unimportant, and that is why I made the point that the VPN client is unaffected by this process in my closing comments. Thank you for clarifying!
