VPN Error 732 Could not agree on PPP protocols

Hi Vic,
MSCHAP has been deprecated in Vista. It was supported on XP. To get your
connections to work you need to have MSCHAPv2 enabled on Vista and also on
the server. THe other option is to use CHAP or PAP protocols for
authentication. However, these are much less secure than MSCHAPv2. Microsoft
recommends MSCHAPv2.

thanks

had the same 732 error as above. We have been using the built in Windows XP VPN client to connect to our Cisco PIX 506e for years. We got our first Vista laptop a few weeks ago and tried to VPN in...no dice. Tried every setting (PAP, CHAP, MSCHAP) and scoured the internet for a solution. Finally paid the $259 and contacted Microsoft support. After four hours of trying every setting, scouring the internet, and consulting with his mentor the MS tech said I would have to upgrade my PIX IOS to version 7 because it supports MSCHAP version 2. I went to the Cisco site to download IOS 7 and learned that the PIX 506e does not support IOS 7.(cisco site: http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_qanda_i...09186a0). So to sum it up...if you have a PIX 506e and try to connect with VPN using Vista your out of luck. Microsoft refunded the $259.

Correction, there is a way to VPN using Vista and a PIX 506e. The easiest thing to do is to log on to your PIX using the PDM browser interface. Go to Wizards>VPN Wizard>select Remote Access VPN>select Cisco VPN Client>enter a Group Name and enter your PreShared key...etc. (same as you used for your Win XP PPTP VPN). Then download the Cisco VPN Client from Cisco.com. Enter your Group name, PIX IP address, and the password you assigned in the wizard. Bam!
