First make sure all your computers are members of the same workgroup.
Enable NetBIOS over TCP/IP in the properties of IPv4, in the properties of your network adapter
Set the startup type of the TCP/IP NetBIOS Helper service to automatic and start it. (services.msc)
Likewise with the Computer Browser service.
WINS, NetBIOS and lmhosts are responsible for resolving ComputerNames to IP Addresses
DNS and hosts are responsible for resolving FQDNs (Fully Qualified Domain Names) to IP Addresses.
