Unmanaged dll call error from IIS asp.net site

    I’m trying to use an unmanaged C dll from a ASP.NET 2.0 web application
    using p/Invoke platform (dllImport attribute). The asp.net page instances a
    c# library and this loads the C dll.
    I’ve used this dll from a windows application without problems. But if this
    dll is invoked from a Web site it always return this error:
    “Attempted to read or write protected memory. This is often an indication
    that other memory is corruptâ€
    When I use it from a web project using the web server of Visual Studio 2005
    Environment it runs fine, but I’ cant use it in a IIS Web. It is not a
    programming error, all methods invoked returns this error when are called
    from IIS Web site.
    What do I have to configure to allow my web site to call unmanaged dlls?
    I really need help.
    Thanks a lot.
