![]() Typically, this was done by parsing the outcome of the command for lines indicating a failure (e.g., “Request timed out”) or success (e.g., “Reply from”). Unfortunately, until recently, testing results of the PING command executed as part of a script required fairly cumbersome workarounds. This type of approach saves time and computing power. You can simply log the attempt as unsuccessful and repeat the same process with the next computer. If this test fails, there is no reason to continue the connection attempt. This determination comes in very handy if, for example, a specific task must be performed repetitively on a large number of computers.īefore the task is executed (which typically happens as the result of a communication session on a higher level in terms of the OSI model), you can test the basic (network layer) connectivity. The packets’ return to originating computer enables the user to determine not only existence of the network path to the remote computer, but also a number of its characteristics, such as speed and reliability. ![]() In such cases, the most commonly performed test is running the PING program, which generates one or more ICMP packets. The article also features a sample script that retrieves various connection-related statistics. Marcin Policht’s latest article explains how to use the properties of Win32_PingStatus class to test network connectivity. When writing a script to perform a task on a remote computer, it is beneficial to know whether a network connection to this computer can be established.
