Specify an individual computer

The computer name that you type can be an IP address, a URL such as service.symantec.com, or a Microsoft Network computer name, such as Mojave. You can find the names of computers on your local network in Network Neighborhood or Network Places on your Windows desktop.

wIf you don’t have TCP/IP bound to Client for Microsoft Networks in Windows Network Properties, you must use IP addresses instead of names for the computers on your local network.
