Accessing Files on a UNC File Share
If your application needs to access files on a Universal Naming Convention
(UNC) share using ASP.NET, it is important to add NTFS permissions to the
share's folder. You will also need to set the share's permissions to grant
at least read access to either the ASP.NET process account or the
impersonated identity (if your application is configured for impersonation).
