| The previous section discusses using diagnostic tools with recovery tools in order to resolve an issue with a -694 error in synchronization. The technique for combining diagnostic tools and recovery tools is really no different from the process of combining any of the other tools. Using diagnostic tools and recovery tools together in the recovery phase of the troubleshooting process provides more flexibility than categorizing each of the tools and using them only during specific phases of the process. Troubleshooting is an iterative process that sometimes involves many trips through the process of examining the problem, making a change, looking at the result, and reexamining the problem to see whether it has been resolved. As with other combinations of tools, knowing the features and functionality of each tool is critical. If you are using tools that produce output or take input, knowing what the formats are and how to convert them is also a significant part of getting the tools to work together. Chapter 11 examines a situation that calls for the combination of NList and UImport to recover lost group membership information. This idea of combining tools is central to resolving critical DS issues. If you don't effectively use the tools you have at hand, your troubleshooting approach is more likely to be disorganized and take longer than necessary to resolve the issue. |
