I have a baisc ASP.Net Application which displays the contents of a given file structure via a web page using system.io. In Web.config impersonation is set to true and authentication to windows. On IIS anonymous access is denied to the application and any virtual directories my application may be pointing at - some are local and some are remote(connect as property set to a domain account with relevant access to read file structure). When accessing the application locally to the server it works fine, when accessing the application remotely authentication boxes appear and access denied errors to the remote virtual directories are displayed.

Is there a maximum number of hops impersonation can make? am i missing the point with impersonation here? any advice would be gratefuly received!!!!
