Summary

This chapter summarized common TCP/IP related problems. We learned quite a bit about major TCP/IP faults and methods of correcting them. You learned to troubleshoot a TCP/IP network by first checking lower-level functions, such as link reliability, and then to progress to IP connectivity checks, and routing and name resolution tests. We discussed the typical symptoms of some TCP/IP related problems. Understanding the symptoms, you can frequently solve network problems without even touching a machine.
