Vista-Lenovo X61 Tablet-IntelPro Wireless – LEAP

I am testing a Lenovo X61 tablet on a domain. It has a Wireless Intel Pro Internal card, has Vista installed. We use LEAP for security. When setting up the wireless connection via Access Connections or Windows Vista, or the Intel Pro software, LEAP is not an option, although it is on all of our XP machines with the same card using Access Connections. Thank you in advance for your assistance.
