# Failure to Schedule Inventory Scanning

## Problem

You have scheduled Inventory Scanning, but it failed.

1. Go to *Start* and select *Control Panel*.

3. Select the *Exceptions tab*
4. Click on *Add Port* button and add the ports as 8020 or your server http port and 8383 or your secure https port respectively.
