VPN Connection...failed. The error...is 734.

[Guest]

I cannot connect to my campus VPN using the same settings that work from
Windows XP. How do I diagnose this?

CoID={B3C82F11-36D2-46FE-A4F9-6A6F6329277A}: The user MyPC\Me dialed a
connection named VPN Connection which has failed. The error code returned on
failure is 734.

Thanks,

I think the error is coming from the PPP connection being set to require a
secure password.
Go into the VPN properties. (Just click 'connect to' and wait for the list
to appear. Right click on the VPN entry and choose properties. Choose the
'Security' tab. Untick 'use Windows logon' if ticked. Also untick require
data encryption if it is ticked. Try to connect. If those don't work you
need to go into the advanced security settings at the bottom and set it up
so that unencryted passwords are allowed (PAP). Keep a note of what you
tick/untick so you can put it back to how it is now in case none of this
helps!
I hope that helps.

Thanks. None of that worked. I have a computer running XP with the exact same
VPN connection settings as the Vista computer and it works fine. Oh well. It
is murderously inconvenient but not enough so to justify calling MS support.

Is the VPN to a Windows 2003 VPN (possibly a Cisco emulating such)?
