Installing TNI is simple enough. You download the software from the company's Web site and install it on one PC. You do not need to install it on your other computers, provided they are all connected to the same network.
Getting TNI to survey all the PCs in your network may take time. You may need to adjust software firewalls on your PCs to permit access. And unless you already have a common Windows administration account, you'll need to provide TNI with a valid user account name and password for each networked PC you wish the software to scan.
But after this one-time setup, the scanning wizard requires just a minute or two to survey each PC. When the scan is complete, you can view hardware configuration details, including attached peripheral devices; installed software, including Windows updates; user accounts; and other information such as shared resources like printers and files.
You may opt to manually add additional information for each PC scanned, such as date of purchase, price, and physical location. You can also have TNI prepare reports on any or all of the assets scanned.
