The HEIMDAL Agent allows you to perform a network check that will discover any devices in the network that are not yet running the HEIMDAL Agent. This check can be triggered from the Heimdal Dashboard -> Management -> Active Clients by selecting a device and by choosing Scan non-Heimdal devices from the dropdown menu:
The scan for non-Heimdal devices functionality tells the selected computer to perform a network scan for computers that are not running the HEIMDAL Agent.
How does scanning for non-HEIMDAL devices work?
Once a scan for non-Heimdal devices is selected, the HEIMDAL Agent initiates the scan for non-Heimdal devices in less than 2 minutes (if Realtime Communication is enabled) or immediately after pressing the Sync GP button (within the HEIMDAL Agent). The HEIMDAL Agent will be using the local IP Address and the local Subnet Mask to calculate the IP class for the current Subnet. A nslookup is performed for each discovered IP Address to correlate the Hostname with the IP Address, a ping is used to populate the ARP cache for each IP Address, and an arp -a command is performed to get the MAC address for each IP Address.
This option is available if Allow network scan is enabled in the Group Policy settings and discovers endpoints/devices ONLY if they are registered in the Reverse Lookup Zone of the DNS Server.
