Description: On occasion when troubleshooting networking issues you may need to run a Ping test to see where the if the communication channels are set up correctly. This article will cover how to perform a ping test on a Windows OS.
Access the Windows Command Prompt or Windows PowerShell application and enter the command without the brackets [ ping XXX.XXX.XXX.XXX].Replace the red X's with the IP Address you are attempting to communicate to. This command will send packets of data to the target IP address requesting an echo response. If a response is received, it will output the amount of time the request took. If not, it will timeout. If all requests time out, this could indicate a communication issue with the local network.
Being unable to PING from a computer to another computer usually indicates that the target computer is not receiving the PING request or is configured to not respond. This is a network issue that is the responsibility of the merchant's IT to resolve. The information below is provided to assist in identifying the issue only.
If the ping command does fail, some basic troubleshooting can be suggested
- Verify that the UTG computer up and running
- Run an IPCONFIG, see, How To Run ipconfig To Check For A Static IP Address
- Run the PING from the UTG to ensure it can PING itself. If not, skip to step five
- Verify that the IP addresses of the UTG and terminal are in the same IP scheme by checking the IP addresses and subnet masks
- If the Subnet mask is 255.255.0.0 the first two octets (192.168.x.x.) must match
- If it is 255.255.255.0 the first three (192.168.1.x) must match as the subnet mask defines what part of the address is the "network id" and what part is the "host id"
- If these do not match the machines will not be able to communicate without a router or layer 3 switch between them to route the traffic from one network to another
- Verify that File and Printer Sharing is enabled in Windows on the UTG computer
- With this feature disabled the computer will not answer a PING
- File and Printer Sharing is located in the Windows Control Panel
PING is a tool to resolve a larger issue. If PING is not working simply because it is disabled, it is not an indicator of an issue itself. Other tools such as browser tests and telnet can be used to troubleshoot network communication.
Ping tests are not used for validating if a TCP Port is open, they can only confirm the assigned IP can be found on the local network. If you are attempting to validate whether a specific TCP Port is open or closed you should attempt the UTG Browser Test.
