There are four NetBIOS name resolution modes that tell a client which method to use: B-Node, P-Node, M-Node, and H-Mode The command ipconfig /all displays the current NetBIOS Name Resolution configuration on Windows. .. routers do not forward broadcasts Therefore B-Node name resolution mode will not work in a routed environment 1.5.1.2 P-Node Clients configured to use the P-Node (or point-to-point) mode will use WINS for NetBIOS name resolution Figure 1.21 illustrates P-Node name resolution To use PNode mode, a client must be configured with the IP address of a WINS server When Computer A needs the IP address for Computer...

Why not use 4? 24 -2 = 14 subnets, which is not enough Using 6 bits, 26 -2 = 62 subnets, which works for the subnets but does not... listens for broadcasts from clients configured to use B-Node It takes the request and sends it directly to the WINS server it is configured to use 1.5.1.3 M-Node M-Node (or multiple) mode-configured clients try to resolve NetBIOS names with a broadcast first (B-Node) If the broadcast is not successful, the client tries to resolve the NetBIOS names via a WINS server (P-Node) Figure 1.22 illustrates M-Node... site's address into the address bar of your browser, count how long it takes to resolve 1.5 WINS and NetBIOS Names Windows 2000 is the first Microsoft operating system with the capability to rely completely on DNS for name resolution The primary naming system for Microsoft networks before Windows 2000 was based on NetBIOS names A computer's NetBIOS name, sometimes called its "computer name," is assigned... what are the starting and ending IP addresses? Before we answer these questions, I want to introduce you to a little formula that makes life in the IP world easier This formula is 2n -2 Using this formula, one can determine the number of hosts in a subnet 2n represents the number of hosts that can be created, where 2 is the number of possible values for each bit (0 or 1—remember we're dealing in binary... 1.21 P-Node name resolution P-Node resolution works great because it alleviates the two problems associated with B-Node mode: too many broadcasts and not working in a routed environment Since all queries and responses used in P-Node name resolution are directly between the client and the WINS server, no broadcasts take place, which means P-Node mode works in a routed environment Some limitations of P-Node . for several well-known NIC manufacturers.
