The NetBIOS (Windows machine names) protocol back then would only work on the NetBEUI transport protocol. In the older days, you were required to run a WINS server in order to avoid name resolution problems within a Windows network. WINS is an essential part of the Microsoft networking topology. The answer is that each of these services relies on different protocols - they simply work in a very different way. So you might be wondering why are there two different services essentially performing the same job? Ping here uses DNS to resolve to an IP address, e.g 204.45.12.1, while the 'net use' command make use of WINS to resolve the NetBios name 'Jupiter' to an IP address. While both commands are referring to the same name (Jupiter), the difference between them is important. The first one simply sends a ping ( icmp echo) packet to our file server, ensuring it's alive, while the second command calls the same server (Jupiter) in order to connect to a shared folder named 'mainshare.'

The two above commands should look familiar.

To help explain, I'm going to use an example that will ensure you get the right picture on each of these services.Ĭonsider a file server by the name 'Jupiter,' and the following two commands:
