Hi,

I'm working on an ASP.NET application that allows users to upload images to
a central storage area and view using a HTTP handler.

This works great if the files are stored on a local drive on the web server.
The problem I have is that when I move this storage area to a share on
another machine with full permissions for everyone I still get
System.IO.FileNotFoundException.

Are there any other additional other permissions for the ASPNET account on
the web server that need to be set before I can access remote shares?

Many thanks

Hi,

have you try to add the ASPNET group to your share folder permission ?

I have, and it still doesn't work. I'm trying the solution presented at http://www.15seconds.com/issue/030926.htm

Serge,

The machines are not part of a domain so the ASPNET account is only on the
web server and therefore I cannot give permissions to the user directly on
the share.

Going to read article posted by flipdoubt.

Thanks

In a scenario like this, you should use P/Invoke to do code-level
impersonation. You can then impersonate a user (or group) who has access to
that share.

First, the FileNotFoundException doesn't indicate a problem with
permissions. It means that the file cannot be found. In other words, your
path is wrong.

The best way to access a network share is to use a UNC path (e.g.
\\192.168.1.1\c$\somefolder\somefile.txt).

It is possible to see a FileNotFoundException when you are experiencing
permissions problems.

I agree, I can open the file by pasting the UNC into explorer no problem -
just not through ASP.NET

Jim,

I was really trying to avoid having modify the application to impersonate a
user (not lazy just time constraints). So I just opened the share for full
access by everyone but no luck. At this rate it will quicker to re-write the
code.

If you are not impersonating, that means that the worker process account is
being used to access the share. It's possible that it's failing because of
that. I would set a password for the process account and then configure an
identical account on the file server. This will allow for pass-through
authentication.
