Note: When the client gets error -47 or -48, it uses the adjustable ARP Timeout parameter in the

configuration file to set an amount of time to wait before trying again to connect to this non-existent

server. This feature allows the client to continue sending commands and polling other existing

servers, while waiting for the non-existent server to appear on the network.
