You work for a small city IT department and you have a custo

You work for a small city IT department, and you have a customer in City Hall who can print to a network printer and access a shared folder on a coworker’s computer but who can’t connect to a remote file share in another city department across town. She also can’t connect to the Internet. What do you suspect?

A. The DHCP settings on the customer’s computer are wrong.

B. The DNS settings on the customer’s computer are wrong.

C. The gateway settings on the customer’s computer are wrong.

D. The subnet mask settings on the customer’s computer are wrong.

Solution

C. Since the customer can connect to devices on the local network segment but not to file shares on remote network segments, the most likely problem is that the computer isn’t accessing the correct gateway router to connect to remote network hosts, including those on the Internet. A computer must be either manually or dynamically configured to use the IP address of a gateway router directly connected to its network segment in order to be able to send and receive network traffic to and from remote networks.
