Question

You configured the IP address and DNS name of a new internal web server named WEB3. Your first test from a web browser on your workstation was successful. But when you came to work this morning, you were not able access WEB3 from the same workstation using the same browser. You get an error message stating that this site cannot be reached.

You have not changed the server's IP configuration since the successful test the night before.

Which troubleshooting step should you try first to discover what the problem might be?

Answer 1

I would reset the Domain Name System (DNS)

Step-by-step explanation:

One factor that could lead to the "Site Cannot Be Reached" error is DNS "poisoning". Another is invalid DNS cache. Both can be caused by an attack on the system by people trying to spoof the system. Spoofing ensures that even when the right address is entered, it leads one to another web address.

One way to quickly reset the DNS is to run ipconfig /flushdns

This helps to clear the DNS cache.

Once the DNS cache has been successfully flushed, the system returns a confirmatory message that reads “flushed the DNS resolver cache”.

The systems administrator can now proceed to reconfigure the IP address(es)
