Because the web service is being hosted by IIS, the user id underwhich IIS is
running will need to be given access. That is normally ASPNET, but it really
depends on how you've configured the web site. If you have impersonation
setup, then it would be the user who is accessing the service.
Once you have identified the user, give that user read access to the
directory that contains your configuration file.
Hope that helps.
