Troubleshooting Your Network From time to time you may experience problems on your network. Often, you can easily diagnose and correct the problems without the need to contact a Hewlett-Packard service representative. You may choose to perform some troubleshooting operations on your own, following the guidelines provided in this manual. Troubleshooting Process Overview When problems occur, it is helpful to follow a logical process of characterizing and identifying the problem so that you can determine the appropriate course of action to take. Chapter 4 of this manual suggests a process to follow when troubleshooting problems with network connections. Chapter 5 summarizes most of the common types of problems that might occur on your network. Once you have identified the problem following the process described in chapter 4, use chapter 5 as a guide to the actions you can take to resolve the problem. If you are unable to identify or resolve a network problem using the information provided in chapters 4 and 5 of this manual, consult your Hewlett-Packard service representative. Tools Hewlett-Packard provides a range of tools to help you perform line verification or run software or hardware diagnostics. You run most of the network diagnostic tools using the NETTOOL utility. NETTOOL provides a set of core functions and an interface for running software and line verification tools that were run standalone on earlier versions of MPE. Help information is available when you use NETTOOL. You can also develop your own tools to run as part of the NETTOOL package. See chapter 6 for a complete discussion of NETTOOL and instructions for using each of the NETTOOL diagnostics.
