The Windows service option allows end users to connect to a VPN Router and then they will need to log in to their Windows domain in order to access LAN resources. The Windows GINA option is supported on Windows 2000 and Windows XP operating systems. GINA allows for an automatic Windows domain login service through a VPN tunnel.
