A group of Windows PCs can access local network resources but not the Internet. Which three commands should a technician use to troubleshoot?

The technician's first step in troubleshooting connectivity issues, especially when a group of Windows PCs can access local network resources but not the Internet, involves gathering critical information regarding network configuration and connectivity. The three commands mentioned are effective tools for diagnosing such problems. Using the ping command allows the technician to test connectivity between the local PC and local network resources, as well as to external websites. This is crucial in determining whether the issue is limited to external access or if there are broader connectivity problems. The ipconfig command provides detailed information about the PC's IP configuration, including the assigned IP address, subnet mask, and default gateway. Reviewing this information can help identify misconfigurations that could prevent Internet access, such as an incorrect default gateway. The nslookup command is vital for troubleshooting DNS issues, which are common culprits when Internet access is impaired. It can verify whether a DNS server is reachable and whether domain names can be resolved to their respective IP addresses, something that is necessary for accessing websites. Combining these three commands gives the technician a comprehensive view of both the network configuration and its connectivity status, which is essential in diagnosing and resolving the issue of being unable to access the Internet.
