Netbios over IP

Right click on Network neighborhood, choose properties, click on the protocol tab, you'll see what protocols are installed. Click on the Services tab, then the Network Access Order button; under Network Providers you can see the order in which they're loaded.

Windows NT installs TCP/IP as its default protocol. If you have TCP/IP, you have "NetBIOS over IP" (NBT) installed. In addition, for the above information, you'll need either WINS or an LMHOSTS file and routing information to be configured correctly. Also, connected in what way? One NT Domain? File and Print sharing? Data or application access? Internet access? For full NT Domain connectivity you'll be held captive to the WAN speed. Slow WAN links cause NT domain activities to time out.

Netbios over TCP/IP is installed automatically when you install Microsoft's TCP.

My belief is that netbios will not function over the internet as that requires Sockets e.g. TCP or UDP and and a Port number. HTTP uses TCP Port 80, FTP TCP port 21.

If you have the Resource Kit there is a program called Browstat where you can see the Netbios over TCP/IP.

Finally think back to what you wish to achieve with your internet connection, printing, file transfer, browsing web pages, then research what is the best way to achieve it.
