Network Inventory allows you to collect information on the services registered in the Operating System on any Machine. To get a list of services first of all check the Services option on the Settings tab under the System Information Scan Options. Then select the Machines you want to retrieve a list of services 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 services list for the Machine by selecting its Services child node in the Machine Tree. Pic 1
You can add a service to this list manually, remove the service from this list, edit each service info, export this list to any format or create a report containing this information.
