Publisher Summary The chapter explores low-level tools from the resource kit, available to Microsoft Operations Manager (MOM) for your comfort and advance maintenance. These tools come in handy when troubleshooting a failed MOM infrastructure. However, the most probable cause of errors is not in the Agents but in the server and the management pack rules. The chapter addresses some common issues that often go wrong and need to be addressed first. The chapter also focuses on backing up and restoring the MOM infrastructure, and why it is essential.
