Windows Vista Pre-Logon via VPN

Spanish Keywords: Iniciar una VPN antes del Inicio de Sesión de Windows Vista

Logon to Windows using PLAP (Pre-Logon Access Providers)
I have found that it is possible if A) the computer is joined to the domain, B) you pre-configure a DUN connection, and C) that connection can be used by all users (i.e., is owned by System). Here are the details:


Logon to Windows using PLAP (Pre-Logon Access Providers)

1. Log on as a local admin.
2. Control Panel >> Network and Sharing Center >> Setup up a connection or network >> “Connect to a workplace” OR “Set up a dial-up connection”.
3. Check the checkbox to “Allow other people to use this connection” (so that the owner of the DUN configuration will be System and not your individual user).
4. Complete the wizard and save the connection.
5. Join the PC to a domain (establish a dial-up connection first, if needed).
6. After rebooting, press Ctrl-Alt-Delete to log on if prompted. 
7. You are presented with the logon screen for the user that last logged in. Press Esc or click Switch User to view other logon options.
8. There will now appear a blue button near the lower-right corner, just to the left of the red Shut Down button. 
9. Click the blue button. If you have more than one System-owned DUN configuration, then all of them will appear here as a button that can be clicked, in which case you click the one you want to use.
10. If prompted, type the username and password for the DUN connection and click the round, blue button to connect. 
11. A dialog appears, showing the progress of the connection attempt. 
12. After the connection is established, Windows will use the same credentials to log into Windows. If that fails, you will be taken back to the Windows logon screen to submit Windows credentials.
