Re: Vista 64-Bit VPN/Cisco Problem
Are you using a Cisco firewall?
I'm having a similiar problem with Checkpoint right now. They've been promising a 64-bit client "soon" since June 07 (at least). Right now I just use a XP32 virtual machine whenever I need to log in to work remotely. I'm honestly excited for W2k8-R2 and W7 to roll because of the integrated VPN. Checkpoint is just a mess overall and I wish we didn't have our hands in that product at all.
Good luck, and let me know how NCP works for you. I know there are a few freeware clients that run on 64 bit OSs, but they require a significant amount of intimacy and flexibility with your firewall.
