Computer Inventory Server can gather information from your network PCs through either TCP or WMI. Using the TCP connection, you will need to install the Computer Inventory Client on each PC. Using the WMI connection, it is not necessary to install any client at all. However, the WMI connection gathers a somewhat smaller subset of information excluding, for example, installed software and patches. We would recommend that you use the TCP connection with your clients to get the best and most informative results.
