When monitoring a server with the help of NetBOIS, this LAN monitor periodically connects to the remote computer using the NetBIOS protocol specified in the Server Properties Dialog and alerts the Network Administrator if the computer does not respond:

To allow this lan monitor to periodically check availability of a computer in your LAN please specify the computer's netbios name and the netbios protocol the program will use in the monitoring process. You can also use the Autodetect button to make the program list the netbios protocols installed on both computers and let you select one of them.
