We're having the same problem. We have given write permissions in IIS and directory level write permissions and are still having the same problem. Could you please tell what specific settings are needed in IIS. We are having the same problem on Windows XP and Windows Server 2003.
We're unclear when you state "give permission to the component" . We are not sure what you are referring to as "component" . Do you mean the website, directory...?
Please help and thank you.
