    the asp.net process runs under a special user. that user will not by
    default have rights to resources outside the scope of the web service.
    imagine what would happen if a web service could call ANY code on your
    server. there are many ways to approach this depending on your environment
    and what it is that you are trying to achieve. but at the most basic level,
    you need to give the aspnet user the rights to launch excel.
