Took me a few hours to figure this out, figured I’d pass it along. Forgive formatting, I’m on mobile.

    No, that’s not what it means.

    If the device is wired to the LAN, the admin logon authenticates the user with the domain server, and thus decrypts the files using the credentials that are stored server-side.

    If the drive would be fully encrypted, you’d have to enter a password each time you boot the machine. That can be done, but is really not all that practical, especially not when working with a domain server / remote admin.

    For a private computer, you can have a look at Veracrypt (FOSS) if you want to have a fully encrypted drive.
