Agent does not report to DCAM after you install Microsoft Operations Manager 2000 (870909)


The information in this article applies to:

  • Microsoft Operations Manager 2000

SYMPTOMS

After you install Microsoft Operations Manager (MOM) 2000 on a server, the MOM agent does not report to the Data Access Server (DAS) or the Consolidator and Agent Manager components (CAM).

If you run the netstat -a command on the server, you see many CLOSE_WAITS states.

CAUSE

This problem may occur if you install a MOM 2000 server or DCAM on a computer that already has the stand-alone MOM agent installed. The problem occurs because the MOM agent and DCAM are configured to use the same database and configuration group. The MOM 2000 server believes it is both a CAM and a stand-alone agent.

You may experience this problem in environments where the MOM agent is preloaded as part of a server image.

RESOLUTION

To resolve this problem, remove the MOM agent from the server where you want to install DCAM or other server software. To remove a remotely-installed agent, follow these steps:
  1. Start the MOM Administrator console.
  2. Expand Configuration, and then click Agent Managers.
  3. Right-click the Agent Manager, and then click Properties.
  4. On the Managed Computers tab, click the agent that you want to remove, and then click Uninstall Now.
To remove a manually-installed agent, follow these steps:
  1. Use an administrator account to log on to the agent computer.
  2. Close all open applications.
  3. Click Add/Remove Programs in Control Panel.
  4. Click Operations Manager Agent, and then click Change/Remove.
  5. If you manually installed this agent to more than one configuration group on this computer, specify the appropriate options in Remove Multiple Configurations, and then click Next.
  6. Click Next in Perform Uninstall, and then click Continue.

    Note The removal program might take several minutes to complete. Although the removal program might appear to stop responding for several minutes, do not end the process.
  7. On the computer where DCAM is installed, remove that computer from the Managed Computer rules. To do this, follow these steps:
    1. Start the MOM Administrator console.
    2. Expand Configuration, and then click Agent Managers.
    3. Right-click the Agent Manager, and then click Properties.
    4. On the Managed Computer Rules tab, click the agent that you want to remove, and then click Delete.
  8. Delete the computer name from the ManualMC.txt file. The ManualMC.txt is stored in the Program files\Microsoft Operations Manager 2000\OnePoint folder on the DCAM computer.
  9. Delete the MOM agent computer from the computer groups. If the global Agent Manager properties are set to Automatically install and uninstall agents as required, DCAM automatically performs this step. If this option is not set, you must perform this step manually. To delete the agent computer from a computer group, follow these steps:
    1. In the MOM Administrator console, expand Rules, and then click Computer groups.
    2. Right-click a computer group, and then click Properties.
    3. On the Included Computers tab, click the computer that you want to remove, and then click Remove.

WORKAROUND

To work around this problem, periodically stop and then restart the OnePoint service on the MOM 2000 server.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
