Ping messages (ICMP) are frequently blocked for servers. If you have control over the hosts, you can be sure to enable it. But ping doesn't mean the services are running, it only means that the server OS is running. The best way to check for an alive host is to try a connection to the host, connection to the application that you must verify. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
