Importing Hosts from Network Neighborhood
To add one or more new devices to the existing network map from the network neighborhood, select the item Import hosts | From network neighborhood on the map's context menu. The Network tree window will appear on the screen. Select computers to be added to the map by selecting checkboxes with computer names and click OK. The objects will be added to the map.
You are able to add only new hosts to the map by enabling the Add new hosts only option on the lower part of the window. This feature helps to keep your maps actual even if your network is big and grows fast.
