If a user can ping a web server successfully but cannot browse it, what is the most likely problem?

Router issues
Incorrect DNS server address
Firewall settings
Internet connectivity

The correct answer is: Incorrect DNS server address

If a user can successfully ping a web server but encounters issues when trying to browse it, this typically indicates that the server is reachable at the network level, but there may be a problem with resolving the domain name to the corresponding IP address. In this scenario, an incorrect DNS server address could prevent the user’s browser from translating the website’s domain name into its numeric IP address. While the user can ping the server using its IP address directly—which demonstrates that network connectivity exists—browsing requires proper name resolution to access the website using its domain name. If the DNS is incorrectly configured (for example, if the user is using a DNS server that is down or incorrect), the system wouldn’t be able to resolve the domain name, leading to an inability to browse the website. Other issues, like router problems or firewall settings, could potentially prevent access, but they would likely cause connectivity issues beyond just browsing, affecting the ability to ping the server as well. Similarly, internet connectivity problems, if present, would also manifest more broadly than just browsing issues. Thus, the most likely cause of the specific problem described is indeed an incorrect DNS server address.
