Why is my ping name resolution not working?

If the ping by name fails, try a ping by IP address. If this fails, the local and remote systems don't have network connectivity between them. The issue could be a cable, switch, router or firewall problem. If the ping by IP address succeeds but the ping by name fails, it's probably a name resolution problem.
