Summary
Effective troubleshooting combines instinct, experience, andstructured techniques to identify, locate, and correct network or computer problems.
Documentation is essential in effective troubleshooting, and shouldcontain baseline information about the network.
A large proportion of networking problems relate to physicalcomponents.
Many networking problems can be identified with software utilitiessuch as ping, tracert, and netstat.
In a network containing both wired and wireless connections, it isimportant to isolate the problem to either the wired or wirelessnetwork.
