Troubleshooting
What to do if the ping did not work
1 Ensure that you entered the IP address correctly.
2 Ensure that the subnet mask and default gateway are properly configured
on the device you are pinging.
Confirm this by viewing the IP Configuration property sheet for the device.
3 Ping the device's gateway.
4 If the gateway does not respond, ping a known good device on the device's
network.
5 Contact your data network administrator. There may be a configuration
error elsewhere on the network.
