NRI fails to upload discovered inventory from the target machine. This error occurs after selecting either "Basic Scan", "Advanced Inventory Scan", or "Register Asset". The scan runs and looks normal, but fails upon completion while trying to upload the inventory to the manager.
Make sure the "NRIReceivedReports" folder exists in the root of the DSM directory on the Domain Manager.
If it does not exist, create it under the DSM folder. (Default - ..\Program Files\CA\DSM\NRIReceivedReports)
This folder must be fully accessible by the Internet Guest Account as shown in the screen shot below.
