Manage Discovery configuration
Note
“Ping” discovery will always be performed for any defined IP address range.
Network discovery
An Inventory server can be configured to perform network discovery on specific IP address ranges using the following technologies: SNMP, SSH, WinRPC/WMI, ICMP, DNS lookup, TCP/IP fingerprinting, and NIC manufacturer lookup.
Note
When using TCP/IP fingerprinting, the ports of the Inventory server must be opened for all incoming TCP/IP traffic destined for the application snowserver.exe.

Active Directory Discovery
An Inventory server can be configured to perform Active Directory discovery using LDAP or secure LDAP. Information on both devices and users can be gathered, and multiple LDAP paths can be configured.
Depending on the size of the network to be discovered, it will take some time for the devices to appear in the Discovery view of the Admin Console.
Information on users will be gathered and stored in the Inventory Server database, but it will not be visible in the user interface of the Admin Console.
