A computer can successfully ping outside the local network, but cannot access any World Wide Web services. What is the most probable cause of this problem?
- Windows Firewall is blocking port 80.
- Windows Firewall blocks port 23 by default.
- The computer network interface card is faulty.
- The BIOS or CMOS settings are blocking web access.
| Explanation & Hint:
The World Wide Web (HTTP) protocol uses port 80; port 23 is used by Telnet. Successful pings to other devices indicate that the network interface card is working correctly. BIOS and CMOS settings control system hardware functions, not network applications such as the World Wide Web. |
