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.
