i have an ASP.NET website which is using a filestream to read in a PDF image from a UNC share on a remote server 2003 box.
i attempt to load the file on the site (which simply embeds a PDF viewer on the site) but when i debug the code, it's throwing a security exception when i attempt to access the file. saying "access to ___ path is denied".
so... i granted access to the UNC path directory to the ASPNET user. i also granted access to the user that's specified for anonymous access in the site itself in IIS.
nothing.
however, i grant "everybody" access and the file comes through.
so, i need to know WHO is trying to access the file. the assumption is either the ASPNET user or the anonymous user setup in IIS. neither of which is gaining access. i tried to set up file auditing on the server2003 box but it's not logging a failure in the security event log when i get an access denied exception.

I have a webpage that you pass in an id parameter (via a querystring), which it then uses to fetch data from a database. Typically, a user would navigate to this page from another page that lists only those records that the user has access to. However, if they go directly to the page by typing in the URL in the Address Bar, they can effectively view any record they like. to type something like http://localhost/TestSite/ClientAdmin/ManageLocation.aspx?LocationID=5 into their Address Bar, they can access the database record with the LocationID equal to five - even though they shouldn't have access to it
