RadAsyncUpload does not have permission to write files in the TemporaryFolder

[balaji]

Hi Team,
We developed Multiple fileupload feature using RadAsyncUpload  control. Telerik dll version is 2012.1.411.35.
We provided shared location path for TargetFolder and TemporaryFolder of RadAsyncUpload  control with Authenticated Users and EveryOne. But still we are getting below error.
In my Environment, we have 4 web front end servers. So we created a shared location in seperate server and assigned to Target and Temporary Folders. If I am wrong please guide me. Could you please help me asap.

And also we have one more question what account is it using to upload a files in Temp and Target folders. I mean login user or system account or network service...etc..?

Error:
System.Exception: RadAsyncUpload does not have permission to write files in the TemporaryFolder. In Medium Trust scenarios, the TemporaryFolder should be a subfolder of the Application Path.    at Telerik.Web.UI.RadAsyncUpload.TestTemporaryFolderPermissions()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Control.PreRenderRecursiveInternal()     at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyn... 2089f4ca-c105-4340-ab32-ac3565390869

Note: In DEV environment its working fine with authenticated users. with shared location as well as normal folder path.

Thanks in Advance.

Hello,

Thank you for contacting Telerik support.

The error message says:
RadAsyncUpload does not have permission to write files in the TemporaryFolder. In Medium Trust scenarios, the TemporaryFolder should be a subfolder of the Application Path. 

Please make sure that both machines have write permissions to these folders. if is needed you can use the standard aspnet upload to verify that.

Let me know if I can assist you further.
