The windows network neighborhood uses a specific way to map all computers within the network, which other OSs generally will not use because it requires extra ports and services to be running on all computers.

The ubuntu places -> network options displays recently connected network locations such as nfs shares, windows files hares, ftp sites, etc.. , to add a location to that panel you only need to connect to it.

Your best bet to map you network would be to use a program like lanmap2 (https://github.com/pizza/lanmap2).
