The Options window can be opened by clicking the corresponding button in the top right corner of the program.


Change the interface language, date format and currency settings.

Check the online status of assets periodically: automatic pinging of network nodes every few seconds.

Handling of dynamic IP addresses: choose how to resolve hostnames when pinging devices in a DHCP network, or disable the resolution and use the known IP address every time.

You can also configure the synchronization with Active Directory.


Settings that control the scanner's behavior, as well as the default asset distinction and snapshot auto-deletion policies for storages.

Network discovery settings

Network discovery allows you to quickly find assets within a scan task. TNI discovers assets by pinging them.

Use network discovery: if this option is disabled, all network nodes will be scanned by open ports without using ICMP and ARP ping.

For example, if you disable network discovery and add the IP range —, the program will attempt to scan all nodes within this range.

You can choose from two discovery methods:

Classic engine is based on the discovery mechanism built into TNI. You can set the number of ping attempts, timeout and select one of the following profiles:

    • Quick (shallow): asynchronous ping of IP ranges and networks only. Useful for very large ranges.
    • Normal: asynchronous ping + normal ping. A bit slower, but more thorough.
    • Slow: includes both asynchronous ping and normal ping, plus also scans TCP-ports of the nodes that don't respond to ping.

Do not use the Slow profile if you have any intrusion detection/protection system in your network. For example, Symantec Endpoint Protection.

Nmap engine is based on the capabilities of the Nmap utility. You can enter custom Nmap parameters for the ping.

The Nmap utility is not included in the Total Network Inventory package and should be installed separately or already present in the system.

General ping settings allow you enable or disable ARP ping.


Here, the settings for printable reports and group summaries are presented.

Network map

This page allows to edit settings that are common for every network map that you create, such as the autosave and font settings.

More on the Network map.


On this page, you can enable, disable and set up the individual alerts.

More on alerts.


The settings for automatic data import are available here. It may be used to import logon script scan results or periodically updated results of external network scans in cases where no access to these networks is available from the current location. This page allows you to set up automatic import of data when the program starts or at regular intervals.

More on data import.

Logon script

This page serves as a tool for exporting the standalone scanner and for generating a command line for the Logon script scan.


Choose the way in which the Action list (available from the Network tree context menus) behaves and access the editable custom actions file. Also, here you'll find a summary of all templates and keywords of the action definition syntax: click to copy or hover with your mouse to view a hint.

See Actions.


Enable or disable the full SNMP scan from this page. This mode allows to collect complete SNMP information from SNMP-enabled devices (i.e. perform an SNMPWalk). When this mode is disabled, only some basic information from the system and interfaces sections is collected.

TNI contains a package with more than 300 standard MIB files. They allow you to decode many fields in the Viewer & reports - SNMP tree section, so that asset's parameters and their values are presented as meaningful information instead of OIDs. From the same options page, you can check whether an updated package is available for download from our server or to let the program check for it at startup.

You can also download additional MIB files from device manufacturers. Additionally, the program will attempt to download any missing MIB files from a few online MIB databases.

Resident agent

Configure the resident agent for deployment to remote Windows computers or export it for manual installation from this page.

Show resident agent deployment controls in the Scanner: allows you to show or hide the following controls in the task management menu on the Scanner tab: Deploy resident agent, Remove resident agent, Set up resident agent.

Run test scan immediately after service start: runs a test scan at the very first start of the service (will not occur thereafter). For manual installation, use the "/testrun" parameter in combination with "/install".

Run a scan every time Windows starts: runs a scan after the OS is loaded.

Since the OS load time can vary on different computers, the resident agent performs a scan 5 minutes after the OS is loaded. Adjust this parameter by editing the "startup-scan-delay = 5" line in the tniwinagent.ini file.

Overwrite the asset file upon rescan: disables adding a time stamp to the INV file that is generated after scanning. If another file with the same name is found in the target directory or on the FTP server when uploading scan results, it will be overwritten.

Export resident agent: copies the agent files to a user-specified folder (used for manual agent deployment). Exports two files: tniwinagent.exe and tniwinagent.ini.

More about the Resident agent here.


Here, you can disable the default prompts to confirm deletion if you find them annoying, or re-enable them if you need a safeguard from deleting objects accidentally.


Here, you can configure the output and the display settings for barcodes. You can also specify a hot key to quickly switch to the barcode search mode.
