Office VPN access from Vista client not working

[dgr72371]

hello,
A person in our office recently upgraded what pc she uses at home to one that had Vista installed. I've tried setting up the Microsoft OS-included VPN and UltraVNC software on it that we use to remotely access our office pcs from home, and I've found out that in past in Win XP when you setup the security of the VPN connection you use the protocol MS-CHAP (the older one, not Version 2). The problem is that in Vista, they've phased out MS-CHAP, it's not available as a VPN security protocol type. I've tried all the other choices it gives and none of them will allow me to successfully connect to the corporate network from home with a Vista-equipped pc.

Do you know what needs to be done to setup the VPN connection in Vista to allow it to successfully connect through the Cisco Pix 506E firewall device to the office network?
thanks,
david

Seems that Vista only supports MSCHAP v2 and the Pix 506E only supports v1. I've read that version 7.0 of the Pix software added support for MSCHAP v2, but the software is not compatible with the 506E. I guess there are a couple of options for you. You could install the Cisco VPN client software on the Vista machine and use that instead of Vista's VPN client. You could set the Pix and Vista to use CHAP or PAP, but CHAP and PAP are not as secure, especially PAP which sends authentication in plain text. Or you could get a new firewall that supports MSCHAP v2. Out of these methods, I would probably try using the Cisco VPN client software.

Heres some links for you to look at regarding Vista and VPN connection problems.
