I'm going to focus on that part.
It would've been really helpful to display the exact error, but I'm assuming that you ASP.NET app cannot access the path.
This fix can very likely be made in file system.
You need to go to the folder where the PDF files are located -- if it is multiple folders try one first and figure out how to change all of them later -- and right click on the folder and select properties.
Next, is the difficult part. You have to know what user your ASP.NET app is running under.
It's probably under the DefaultAppPool in inetmgr (IIS).
Once you know which user your ASP.NET application is running under then that is the user you need to give access to the folder.
Give that user full (read/write) rights while you test. You can figure out the rest and tighten down security later.
