Hey Nigel

Hmmmm, I think it's most definatley down to permissions on the handlers folder, it's just a case of working out which user it is. Can you see which user account your ASPNET process is running under, as it looks like it's that account that needs permissions.

Many thanks

Matt

Hi Matt

I am totally stumped on this one.

From the Event Viewer log below it appear the user account is "ASPNET"

Process information: 
    Process ID: 1056 
    Process name: aspnet_wp.exe 
    Account name: WISA\ASPNET 
 
Request information: 
    Request URL: http://wisa/usercontrols/ExportMedia.ashx?id=1121 
    Request path: /usercontrols/ExportMedia.ashx 
    User host address: 192.168.2.3 
    User:  
    Is authenticated: False 
    Authentication Type:  
    Thread account name: WISA\ASPNET 

I have altered the source code and moved the .js file to the scripts folder and the .ashx file to the usercontrols folder - really just trying to figure out where things are going wrong. I now get the following

Access to the path 'C:\Inetpub\wwwroot\TestSite\usercontrols' is denied.

But the site is running fine, it is only the "right click" - "Export Media" that is causing grief.

I think that XP Pro and not having the granularity of user access on folders is the key problem - I really need a proper web server to facilitate user permissions, etc and to replicate a production environment.

The one thing that I did notice was in the event log above "Is Authenticated: False" is showing up. I am actively logged in to the admin area so would assume I am authenticated.

So I think I will refer to your code and try implementing a custom dashboard control - it may be I end up in the same position, but it is worth trying I guess !

The other aspect is that I want to generate a CSV file (or similar) as part of the download that provides some details on each image within the zip file - it might be best to do this as a separate task for coding simplicities sake !

Cheers

We are getting the same issue on Umbraco 4.7.1.1, IIS 7:

Server Error in '/' Application.

Access to the path 'C:\Data\Websites\Site34\wwwroot\umbraco\theoutfield\exportmedia\handlers' is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'C:\Data\Websites\Site34\wwwroot\umbraco\theoutfield\exportmedia\handlers' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I meant to add. The IIS APPPOOL identity has read / write / execute permissions on that directory (it has it on the entire webroot folder) and the IUSR account has read / execute permissions.

The folder we're trying to download has many sub folders and files.

And to add further, if I try to export a single file / image, it works just fine. Any idea on what the issue could be?

An old one, but for the record, I just had this and it turned out to be a media item with no image file. Deleting this empty media node fixed the permission error.

is working on a reply...
