You can use the Server Status Display to determine whether the server on which you are working can connect to the other servers in the architecture. To view the status of the connections to the other servers, you need to examine the Polls status information (see Polls in the ClearSCADA Guide to the Server Status Tool).
You can also use ICMP Polls to monitor the connection between servers and to differentiate between server and network failures (see Define the ICMP Monitor Settings for a Server).
