Network Troubleshooting
Live Instructor-Led Classroom Training

This 3-day workshop is predicated on the fact that there are three major places where things can go wrong in a network: the workstation, the network itself and the server. The mornings of each day are devoted to understanding the network components in each platform, with specific focus on internal operating system troubleshooting tools available to isolate problems or point to the likely source.

Students spend afternoons debugging workstation and network problems, both single and multiple, per platform. On the morning of the third day, they learn how to isolate a problem to a server. The afternoon of the third day consists of mixed multiple bugs across all platforms which students are asked to find and fix. This last is the loose equivalent of a final examination. The expectation is that students will return to their jobs hoping that something can go wrong, so they can fix it!

This workshop is presented in classroom lecture/discussion style with hands-on labs to reinforce the lecture material. Students completing the class emerge with hands-on experience and a workbook designed to serve as a practical reference back on the job.

Who Should Attend

Personnel responsible for internetworking corporate computing resources. This includes data center personnel, technical and communications supervisors and managers, system and software engineers, and LAN/WAN network support technicians.


Students are expected to have a working knowledge of TCP/IP data networking equating to about six months experience before taking this class. Familiarity with data network protocols, their operation and the OSI Model is assumed.
