CompTIA Network+ N10-008 Practice Question

Checking the DNS server for the specific record of 'www.acme-widgets.com' is the most direct approach since the problem is isolated to one domain, suggesting that there might be an issue with the record in the DNS server being used by the clients. Running a traceroute would provide information on the path taken to the destination but would not solve a DNS resolution issue. Flushing the DNS cache on a single client machine would not resolve an issue affecting multiple users, and renewing the DHCP lease would not impact DNS resolution for a specific site if other external sites are accessible.
