First
check services.msc (just type that into the search box and hit enter) scroll down and check the TCP/IP NetBIOS Helper service, see that it's started and set to automatic (double click it to set the startup type)
Next
type ncpa.cpl into the search box and hit enter select and then right click on your adapter that you are using for this connection, on the resultant page uncheck Internet Protocol Version 6 (TCP/IPv6), then select Internet Protocol Version 4 (TCP/IPv4) and click the properties button below the frame. On the resultant page, click the advanced button and on the resultant page select the WINS tab at the top, near the bottom put a dot in the radio button, next to Enable NetBIOS over TCP/IP and OK your way back out of there.
Finally netbios information does not use the HOSTS file, but rather LMHOSTS but you shouldn't need it for this particular issue.
