    The problem appears to be a CHAP authentication error. Everything I've read
    says this is always a passwork, domain, username problem, or four slashes
    in the domain username combiniation <domain>\\\\<username> rather then two.

    These things are not the problem here. Can anyone make any other suggestions??

    One thing I don't understand is how the MS machine can authenticate by
    machine name when I'm not giving my machine name. Does it default to the
    hostname of my home machine and is that why I'm not getting past CHAP? If
    that's the case how do I make it see a different machine name?

    If the machine name is not necassary for VPN what else could be going on?

    Any help would be greatly appreciated.

    This is the name of the remote machine which you may need to use in

    And why are you sure that your username on the remote system is

    Sorry, how do you know that "these things are not the problem here"?
