    That's the only cause I know of.
    if the IP address was the problem, he would be getting a "not found"
    message rather than "login failed", which implies a connection to the
    database was initiated, but terminated due to improper credentials.

    The customer should check the sql error logs as well as the event logs
    to see if any other errors or warnings are present.
