拒绝访问路径'C：\\ xxx \\ yyy \\ zzz \\ abcd_20120309.pdf'

Question

I have an ASP.Net website and a C# console application (both developed in VS2010). Both upload files to our web server (Windows Server 2003/IIS 6.0). Users logging in to the website can then view and download these files. This works fine in website. But when I try to download files uploaded by the console application, I get the error:

        UnauthorizedAccessException
        Access to the path 'C:\xxx\yyy\zzz\abcd_20120309.pdf' is denied.

I have already manually provided "Full Control" to NETWORK SERVICE account for that folder.

Why is Asp.Net code unable to access a folder created by the console application?

Any idea? Thanks!

Answer 1

You need to provide access to the folder for IIS_IUSRS (or something along this line).

AKA you need access for IIS.

Including access to everyone, doesnt include this user. So it must be done directly.

Network service will not suffice.

If IIS_IUSRS doesnt appear in the list, search for it.

Answer 2

Don't know if it matters in this case but one thing I have seen in the past is:

The application first saves the file in a temporary folder and then moves it to the target folder.

Sometimes, don't know the exact rules, the file access right follows the file in the move. ie the file ends up with the access rights for the temporary folder even in target folder.

Check the access rights on the file and see if it differs from the target folder.
