Since most hosts in modern networks are protected by firewalls, pinging those computers regularly may not work (if the ICMP protocol is disabled). In such cases, checking by opening a TCP connection to a specific port of the host may help. In this case, we can check the availability of computers by attempting to connect to their TCP port 135 (DCOM) or 139 (NetBios). Please send your questions to us.
