A variety of tools and resources are available for diagnosing problems, and the event log, server and client logs, and MMC diagnostic tools, such as the Office Communications Server Logging Tool and Snooper, all make diagnosing problems easier than it has been in the past. Always check the event log before digging into a diagnostic session as well because the problems it identifies can point out—with no further work—exactly what needs to be done. For more information on how to put these tools and resources to work, please see the other chapters in Part V that describe generic and specific troubleshooting steps for various scenarios.
