There is always Plan C...
Get them to set you up with a VPN connection that you can log into from home on your laptop. Then, install
RealVNC onto both your desktop and your laptop. Configure your desktop to run the VNC Program as a Server and your laptop as a Client.
Then, you simply make the VPN connection to work, and using the IP Address of your desktop, log your laptop in as a client. You will go directly to your desktop's desktop. It would be as though you were sitting in front of your work computer.
There is a bit of latency to deal with, but at least you would have access to the files you wanted.
