Troubleshooting can account for up to 90 percent of a network administrator's job, so effective troubleshooting skills will help administrators respond quickly in a crisis situation, and keep their networks running smoothly. It can be a quantum leap from network administrator to troubleshooting guru, but knowing how to implement the right technique at the right time can help administrators take their skills to the next level. The Real- World Network Troubleshooting Manual focuses on the methodology and process of network troubleshooting, and how to apply them in real-life situations. Designed to make any network administrator a troubleshooting expert, the book starts with an overview of some readily available, basic troubleshooting tools. From there, multiple real-world troubleshooting scenarios are covered, from basic problems to more advanced, including what to do if a workstation is unable to surf the Internet, wireless users cannot connect to the network, or a hacker attacks the Web site. Although the primary focus is on the Windows workstation and server environment, many of the troubleshooting scenarios are non-operating system specific and can be applied to any computing environment.
