The error message "Ping request could not find host www.google.com" indicates that the network engineer's PC cannot resolve the hostname www.google.com to its corresponding IP address. This means that there is a problem with the DNS (Domain Name System) service, which is responsible for translating hostnames to IP addresses and vice versa. The DNS service can be provided by internal or external name servers, depending on the network configuration.
The next step the engineer should take is to ping the internal name server functionality, which means to test if the PC can communicate with the name server that is configured in its network settings, and if the name server can resolve internal hostnames, such as those of the company's servers or devices. To do this, the engineer can use the following commands:
* To find out the IP address of the name server, use ipconfig /all and look for the DNS Servers entry.
* To ping the name server, use ping <name server IP address> and check if the packets are sent and received successfully.
* To test the name resolution, use nslookup <internal hostname> and check if the name server returns the correct IP address.
If the ping or the nslookup commands fail, it means that the internal name server is not working properly, and the engineer should troubleshoot the name server configuration or connectivity. If the ping and the nslookup commands succeed, it means that the internal name server is working properly, but there is a problem with the external name resolution, and the engineer should check the internet firewall logs for blocked DNS traffic, or test the website from outside the company.
