On a Windows platform, you can connect to the VPN before you log on to Windows domain.
When selecting start before logon, the VPN Client starts and displays the connection dialog box over the system logon dialog box. You connect to the VPN first and then the connection dialog box goes away. You will see the normal windows logon screen and you log on to the domain. You may also load logon script.
To activate start before logon, follow these steps:
1. Open the VPN Client Options menu and choose Windows Logon Properties.
2. Check Enable start before logon and then click OK.
