Introduction

A Discovery is executed from a designated SIS server using Admin Credentials provided via the Hornbill KeySafe, using one of the various methods provided. Once all the devices have been discovered, dependant on configuration, a ping request will also be sent to each device. The Admin Credentials are further used for access to each devices Inventory (e.g. hardware, operating system, installed programs) using WMI via DCOM or WinRM. On successful completion, the device details will be stored within the ITOM Inventory and can be identified as managed and the Inventory viewed.

The discovery Job will always be executed directly from the SIS server and thus needs to remotely connect with any computers that it discovers to retrieve their details. There are two methods supported, that can be utilised:
  • WinRm
Provides secure and firewall-friendly communications, in order to access WMI. This feature is supported on Windows 2008R2 and later, Windows 7 and later and later.
  • DCOM
Communication relies on Remote Procedure Calls and can be tricky to configure over firewalls.
  • Discovery Mode
The Discover Mode dictates the method that identifies devices on the Network. Each Mode will have specific settings; these will be visible in the Discover Mode Settings. It is only possible to have a single mode per Job use of multiple modes, will require the creation of multiple Jobs.
