The other day I was at home in a somewhat odd situation; I had a VPN connection but I could not, for the life of me, remember the mappings of the network drives from the other side. Also, of course there was no documentation how to do it. A kind soul showed me how to do it in windows.

On your work computer, perform a net use. You should get something like:

C:\Users\laur>net use
New connections will be remembered.


Status       Local     Remote                    Network

-------------------------------------------------------------------------------
              H:        \\vpn.server.int\Homes\LAUR
                                                Microsoft Windows Network
              P:        \\vpn.server.int\DEPT_1\Public
                                                Microsoft Windows Network
              W:        \\vpn.server.int\OUTLOOK\LAUR
                                                Microsoft Windows Network
The command completed successfully.


C:\Users\laur>

Now, all you have to do is write down/email/whatever the network paths (like \\vpn.server.int\Homes\LAUR) and map them from your home computer.
