Dan,
One possible solution would be to allow impersonation for the application,
and then grant read/write access to the account you specifiy for use with
impersonation.
For more information on setting this up, take a look at the following
article:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpgenref/ht
ml/gngrfidentitysection.asp
Let me know if this helps. If not, I will be happy to look into this
further for you.

| I've been working on a simple ASP.Net application. The app reads a couple
of
| real simple XML files from it's local directory. The problem I'm having is
| that the application will not read these files when I disable Allow
| Anonymous Access to the site. It throws an unauthorized error (below).
I've
| tried applying the local ASPNET user to the folder permissions list with
no
| luck.
|
| Since disabling Allow Anonymous Access is a requirement and so is reading
| these xml files, would you know of a solution to this problem or
somewhere I
| can go look.
|
| Thanks in advance for your expertise.
