Thanks Genady Sergeev for the reply. I had tried all following options but still in vain.
Attachment has the exact error I am getting and Following is the web.config entries we have:
<
location allowOverride="true" path="Telerik.RadUploadProgressHandler.ashx">
<
system.web>
<
trust level="Full" originUrl="" />
<authorization>
<
allow users="*"/>
</
authorization >
</
system.web>
