Explanation
The key detail is that the technician can reach one website successfully but not another. Since basic network connectivity is proven to be working (one site loads), the problem is most likely DNS resolution failing for the second site-the browser cannot translate the second site's domain name into an IP address, resulting in a 'Page cannot be displayed' error. nslookup queries DNS servers directly and can confirm whether the specific domain resolves correctly or whether a DNS failure is the root cause. ipconfig (A) shows local adapter configuration but would not explain why one site works and another does not. tracert (B) traces the hop-by-hop route to a destination but requires a resolvable address first. netstat (D) shows active connections and open ports on the local machine, not DNS resolution. ping (E) can test basic connectivity but also requires DNS resolution and is less diagnostic than nslookup for this scenario.
