    With past worms and such, folks have quit returning pings so that's
    not necessarily a bad thing.

    nslookup only tells us that the DNS record and DNS resolution is
    working on your box, and that's a good sign.

    If you're using zonealarm, check the logs. If you see denied outbound
    connections headed to port 22 of the remote server, then you know
    what's blocking thins. If one account works while the other does
    not, it could be that Zonealarm has a notion of per-user firewall
    configuration.

    Given that you can tracert to the box, I strongly suspect ZoneAlarm as
    one of the only things that could be causing your issue, because it is
    the only thing on your system that could restrict a given application
    from getting to the internet for a specific user.
