If only one client is receiving IP addressing information, the technician should verify the DHCP scope as the next troubleshooting step.

The DHCP scope defines the range of IP addresses that the DHCP server can assign to clients. It is possible that the scope is configured incorrectly, and the DHCP server is not assigning IP addresses to all clients.

To verify the DHCP scope, the technician should check the configuration of the DHCP server to ensure that the scope is set up correctly. The technician should also check the event logs on the DHCP server to see if any errors or warnings are being generated.

If the DHCP scope is configured correctly, the technician may need to check the DHCP lease. A DHCP lease is the amount of time that a client is allowed to use an assigned IP address. If the lease time has expired, the client may not be able to obtain a new IP address.

After verifying the DHCP lease, the technician should check the default gateway. The default gateway is the IP address of the router that connects the network to the internet. If the default gateway is misconfigured, clients may not be able to access network resources or the internet.

Finally, the technician should check the DNS zone. DNS (Domain Name System) is responsible for translating domain names into IP addresses. If the DNS zone is not configured correctly, clients may not be able to access network resources or the internet.

Overall, the technician should verify the DHCP scope first, as this is the most likely cause of the problem. If the scope is configured correctly, the technician should move on to the other troubleshooting steps to identify and resolve the issue.
