#### Testing the server-to-client connections After making sure that the Ethernet cabling has been set up properly, make sure you can ping the server from each client computer. Then test the HTTP connection by running WebCTRL Design Server.
Click for details below To ping the server from each client To test the HTTP connection
##### To ping the server from each client Use the Ping utility from each client computer to test its low-level IP communication with the WebCTRL® server. PREREQUISITES An IP network connection between your server and client computers A solid Link light and a flickering LAN light on the WebCTRL® client computers and the Network Interface Card (NIC) of the WebCTRL® server. If either device indicates it is not on the network, see Troubleshooting the Ethernet connections After the link and the LAN lights on the server’s NIC and on the client are lighting properly, ping the WebCTRL® server from each client machine. At the Command Prompt, type the following command: `ping xxx.xxx.xxx.xxx [Enter]`, where `xxx.xxx.xxx.xxx` is the IP address of the device you are pinging. The reply should indicate that a device with address xxx.xxx.xxx.xxx is present and passing IP packets on the network. EXAMPLE For a device with an IP address of 192.168.168.100, type the following: `ping 192.168.168.100` TIP To continuously ping a device, type the following command: `ping xxx.xxx.xxx.xxx -t`. Press Ctrl+C to stop the ping command. If you receive the reply Request timed out or you do not receive a reply, contact the facility’s network administrator to check the NIC, the hub's settings, and the IP configuration settings. You do not have a valid IP connection between the 2 devices.
##### To test the HTTP connection WebCTRL Design Server does not attempt communication with field hardware, so you can isolate client-to-server issues from server-to-field issues. Click Start > All Programs > WebCTRL x.x > WebCTRL Design Server. From each client computer, start the web browser, then type the IP address of the server in the Address field. If the WebCTRL® login screen does not appear, contact the facility's network administrator.
