Which utility should be used to verify the correct DNS server configuration on a Windows client?

To verify the correct DNS server configuration on a Windows client, the utility that should be used is ipconfig. This command-line tool provides detailed network configuration information, including the DNS servers currently being used by the client. When you run the ipconfig command with the "/all" switch, it displays comprehensive details about all network interfaces, including IP addresses, subnet masks, default gateways, and DNS server addresses.

Using ipconfig is essential for troubleshooting network connectivity issues as it helps ensure that the correct DNS servers are configured, allowing the client to resolve domain names into IP addresses effectively. This makes it a go-to tool for network technicians who need to ascertain DNS settings quickly and efficiently.

Other utilities in the options serve different purposes: tracert is mainly used to trace the route packets take to a network destination; ping is used to test the reachability of a host on an IP network; and netstat displays active connections and listening ports on the system. While these tools are valuable for different networking tasks, they do not provide specific information about DNS server configurations like ipconfig does.
