I have a couple of users that require having vpn connections to outside offices.  They are on laptops so they need to have the vpn connections be from their machines rather than from a branch office type setup.

On Windows XP, created just standard pptp vpns.  Connects just fine.  The person at the other end says they can see the connection activity and everything fits.

We just bought a new Vista machine.  Use the exact same settings.  Conection fails with error 919.  Admin at the other end says they show no activity on their firewall at all to even show that we are reaching them.

Our firewall log shows that the traffic is going out just fine.

Any ideas?

Error 919 is an authentication protocol error.  I think you'll find the router the vpn is passing through doesn't support the protocol you'll need to use for VPN on vista.

It was common in the past to use CHAP.  Vista has "depreciated" MSCHAPv1 due to security reasons and has gone with MSCHAPv2.  Some hardware can't support this protocol, which may explain why the firewall on their end isn't seeing it.  It may not be making it past your firewall, or it if it is hitting theirs, it doesn't recognize the MSCHAPv2 protocol.

Here is a Vista VPN troubleshooting guide for you:
