Network Inventory allows you to collect information on the user accounts known by the Operating System on any Machine. To get a list of user accounts first of all check the User Accounts option on the Settings tab under the System Information Scan Options. Then select the Machines you want to retrieve a list of accounts for and choose Update Selected option from the drop-down of the Update button located on the tool bar above the Machine Tree. As soon as the update process completes you are about to see the user accounts list for the Machine by selecting its User Accounts child node in the Machine Tree. Pic 1
You can add a user account to this list manually, remove the user account from this list, edit account info, export this list to any format or create a report containing this information.
