    I have a laptop running Vista Home Basic trying to create a PPTP VPN to a
    Firebox 700 firewall. Every attempt to connect results in a 691 error -
    username or password not valid. There are a number of computers running XP
    and one running Vista Ultimate that have no problem creating the VPN. Does
    anyone know of a reason that Home Basic can't/won't connect?

  2. In most cases, VPN 691 is security issue. Have you tried different username?
    Or this search result may help.

    Yes, I have tried several usernames/passwords which I know are valid on the
    firewall. I've also done a number of searches but haven't turned up anything
    useful yet.

    I'm not familiar with that particular device, but some use the NTLM protocol
    for PPTP VPN authentication and have a problem with NTLMv2 by default used
    in Vista. The following registry change may help.


    If the key doesn't already exist, create a DWORD value named
    LmCompatibilityLevel and set the value to 1,

    OR save the following lines to .reg files and run it.

    Windows Registry Editor Version 5.00
