Hi All, I am facing a strange issue on one of my agent, where the agent was installed earlier but it was greyed out, when checked further MMA service is missing from services.msc but rest of the folders and settings is present. Now when we are trying to reinstall the agent, it fails both manually and from the SCOM console, we also tried repair, it failed again.

So we thought to recreate the MMA service which has helped us to make the server communicate to MS but the server is not getting healthy. We also tried uninstallation of the agent, but again now luck. Now we are getting two event ID frequently on the agent, which are 1102 and 10001.

HealthService Event ID 1102 description says:-

"The description for Event ID 1102 from source HealthService cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."

HealthService Event 10001 description says:-

"The description for Event ID 10001 from source HealthService cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."

Can anyone help me fix this issue?

Thanks in advance.

    Hello,

    We can try forcibly removing steps to see if it helps.

    Note: it changes registry, as always, please backup registry before making changes

    1. Download MSIZAP and copy to a location on the affected computer.
    2. Find the product code, which is a GUID that is required for the MSIZAP product code switch.  This can be found by opening the registry and navigating to:HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

    With the Uninstall key highlighted, click on Edit > Find, and look for the string System Center Operations Manager.  Open the UninstallString string value and copy the GUID.  Include the squiggly brackets.

    1. Open an elevated command prompt and run the program as follows:

    msizap.exe t {product code}

    Examples:

    SCOM 2007 product code 25097770-2B1F-49F6-AB9D-1C708B96262A

    SCOM 2012 product code 5155DCF6-A1B5-4882-A670-60BF9FCFD688

    Wait until this process has completed.

    1. Delete the SCOM program files, usually located under “%ProgramFiles%\System Center Operations Manager 2007”. Some files may be locked those can be ignored.
    2. Open the registry, search for the Management Group name
    3. Delete the Microsoft Operations Manager key that the management group name is part of

    7.Open the registry and navigate to:

    HKLM\System\CurrentControlSet\Services

    Delete the following registry entries:

    healthservice
    opsmgr*
    MOMConnector
    8. Reboot the server

    You will now be able to install your agent manually or with your console.

    Regards,

    Alex
