    I have a file explorer on a page, it works on dev and test.  In production I can upload files, delete files, but when I try and open files I get a 401 Error.  
    Why would opening the file be causing this issue when I can do everything else.

    Hi Frank,

    I have already answered your support ticket on the subject, for convenience I will paste my answer here as well:

    When using RadFileExplorer with impersonation you need to apply impersonation to the Telerik.Web.UI.WebResource handler and the handler used by the control (if any), e.g.:
    web.config
    <    location path="Telerik.Web.UI.WebResource.axd" allowOverride="true">
       <system.web>
         <identity impersonate="true" userName="HostingServer\userName" password="userPassword"/>
         <authorization>
           <allow users="*"/>
         </authorization>
       </system.web>
     </location>

    In case you are using a custom FileBrowserContentProvider in your application, you will need to add also permissions for its handler:
    <location path="FileSystemHandler.ashx" allowOverride="true">
        <system.web>
           <authorization>
                <allow roles="*"/>
            </authorization>
        </system.web>
    </location>

    I hope this helps.

    I have added IIS_IUSRS to have full control over the folders where the files exists

    Here are my settings
    In iis app pool the Identity is NetworkService.  In the parent folder where the files are located IIS_IUSRS has full control. 

    I can upload to the folders,  I can delete from the folders.  I have Handler.ashx that downloads pdf rather than loads them on the screen and it works.  It is only an issue when the user tries to open a jpg or other non handled files types in the browser.

    Why would it not use IIS_IUSER permission setting?

    Hello Frank,

    May I ask you to test the permissions of the problematic files, following the approach from this help article?

    Could you also provided more detailed information on the exact scenario the error occurs?
    • Is your FileExplorer working with a custom content provider?
    • What logic are you using for file downloading? Is it the one from this live demo or you have your custom implementation for it?

    Can you prepare a sample fully runnable project demonstrating the configuration leading to the undesired behavior?

    Looking forward to hearing from you,
