Network problems are apt to be unique and sometimes difficult to resolve. Troubleshooting is an important part of maintaining a stable, reliable network service.

This chapter discusses the tools you can use to ensure that the network is in good running condition. However, good tools are not enough. No troubleshooting tool is effective if applied haphazardly. Effective troubleshooting requires a methodical approach to the problem and a basic understanding of how the network works. So we’ll start our discussion by looking at ways to approach a network problem.
