256986 Description of the Microsoft Windows registry



SUMMARY
This article describes how to completely remove a typical installation of Microsoft Operations Manager (MOM) if removal becomes necessary.



MORE INFORMATION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Note The following NetIQ products use some of the same registry keys as MOM uses. If one or more of these products are installed on your computer and if you delete the registry keys as described in the following the steps, these products will no longer function correctly.
 * Security Manager 5.0 and earlier versions
 * Directory Resource Administrator, all versions
 * File Security Administrator, all versions
 * Directory Security Administrator, all versions
 * Exchange Administrator, all versions

The term &quot;typical installation&quot; implies that all of the MOM components (DCAM, Database, Reporting, Web Console, Agent Manager, and Consolidator) are installed on a single computer and that Microsoft SQL Server is being used to host the database.

To completely remove a typical installation of MOM:  Remove all MOM agents (except for the agent on the DCAM; it will be removed when the MOM site is removed).

To remove all agents from computers in the Managed Computers list of an Agent Manager:  Start the MOM console, expand Microsoft Operations Manager (default), and then expand Configuration. Click Agent Managers. In the right pane, click an Agent Manager that has agents that you want to remove. Click Action on the menu bar, and then click Modify Managed Computer Rules on the Action menu. For each rule on the Managed Computer Rules tab, click the rule, click Delete, and then click OK.

Note that if you do not delete the Managed Computer rules, the agents that you remove are reinstalled when the next Managed Computer scan runs.</li> In the right pane, click the Agent Manager that has the agents that you want to remove.</li> Click Action on the menu bar, and then click All Tasks on the Action menu.</li> Click Uninstall Managed Agents.</li> Repeat steps b. through h. for every Agent Manager to remove all agents from all Agent Managers in the configuration group.

Wait until Agent Manager has had time to remove all agents before you proceed to the next step. The Managed Computer tab under Agent Manager Properties shows you the installation state of each managed computer.

If Agent Manager does not successfully remove all MOM agents, refer to the following article for information about how to manually remove a MOM agent:
