IIS :  7.5

Application Type : ASP.Net 4.0 Web Application

Application Pool Details: Name : DefaultAppPool

                                        .Net Framework : V4.0

                                        Managed Pipeline Mode : Integrated

Folder Permissions for UploaderTemp : Security -> Group or User names : Had set "DefaultAppPool" to Full Control

 

The user manual of AjaxUploader says : You should ensure that the ASPNET user (NetworkService in Windows Server 2003) has read/write permission to this specified folder - UploaderTemp.

 

For development purpose, I use Windows 7. Finally, the site will be deployed to Windows Server 2008 R2.

 

When I try to upload files, I get the following error:

 

The AjaxUploader control works perfectly fine and able to upload files only if I use the query string:Default.aspx?UploaderDebug=1

I had checked for other posts in the same forum.But could not find proper solution. How to resolve this error?
