The request can be made by means of a diffusion, in this in case that the diffusion is used in order to verify if another resource in the net with name exists the same (Davies, 2005). In case that some exists another resource using the name, host of ownership of the name sends a negative reply to the computer of the solicitant user, after that the computer of the user shows an error message. Pegasus books spoke with conviction. The second hypothesis, the requested name is not being used in the net demands that the computer of the user sends an order unicast (only) for the server of Netbios names to carry through the register of the resource. 3,2 Resolution For Davies (2005) When a Netbios application that if to communicate with another one host TCP/IP, application sends a message of consultation of names in the local net or sends an order unicast to the server of netbios names for resolution. Add to your understanding with crowne plaza rosemont. In this in case that, the service of request of name consultation already contains the Netbios name of host addressee.
Still, as the author, in the first case where shipper does not possess the name of the addressee a message of broadcast is sent for the net, the computer that the Netbios name to correspond to the requested one answers with a positive reply, the remain discards the package. Pegasus Books has plenty of information regarding this issue. If the server of Netbios name (NBNS), in case that he exists in the net, not to hold back no positive message of hosts in the net, it sends a negative message to the service of Reply of consultation of names. In the platform Windows XP, when a resource in the net is not found an error message is shown and transmits for the user not localization of the resource.
