How to Repair SCOM Agents on Windows Computers
In this post I will cover three methods to repair the Operations Manager agents. They are listed below.
- Repair OM agents using Operations Console.
- Repair OM agents using MOMAgent.msi – using setup wizard and command line.
How to Repair Operations Manager agents using Operations Console
To repair operations manager agents using SCOM console, launch the operations console. Ensure you are using an account that is a member of the Operations Manager Administrators role. In other words this account must have administrative rights on the computer for the repair to succeed.
Out of all the three methods, repairing the agents using SCOM console is easiest one. This is because the other methods involve logging in to the client computer and performing the actions. Hence I suggest use the console to repair the SCOM agents.
Launch SCOM console. Click Administration and navigate to Device Management\Agent Managed. In the Agent Managed pane, select computer you want to repair the agent on, right-click and select Repair.
In the Repair Agents dialog box, either select Use selected Management Server Action Account or Other user account.
Click Repair.
To monitor the repair progress, you can go to Agent Management Task Status dialog box. Here look at the status for each selected computer, it changes from Queued to Success. Success means the computers are ready to be managed.
Repair SCOM agents using MOMAgent.msi setup wizard
The second method to repair operations manager agent is by using the MOMAgent.msi setup wizard.
On the client machine, launch Control Panel. Click Programs and Features and right click Microsoft Monitoring agent. You get two options – Uninstall and Change. Click Change.
On the Microsoft Monitoring Agent setup wizard, click Next.
In the Program Maintenance page, select Repair, and then click Next.
On the Ready to Repair the Program page, click Install.
On completing the Microsoft Monitoring Agent Setup Wizard page, click Finish.
Repair SCOM agents using MOMAgent.msi command line
The third method to repair the OM agents is using the MOMAgent.msi command line. Copy the SCOM agent setup files from Operations Manager installation source to a folder on client computer.
For example in my case the SCOM agent setup files are copied over to scom folder on desktop.
On the client computer run the command prompt as administrator. Change the path to scom agent source folder. Type the below command to repair the agent.
MsiExec.exe /f {CEB9E45B-2152-4C10-A022-0825B53B632F}
You can get the uninstall string here. Replace {CEB9E45B-2152-4C10-A022-0825B53B632F} with the key present on your machine.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
You can also repair the agent using the below command.
msiexec.exe /f MOMAgent.msi /qb
You must restart your computer after the agent repair is complete.
SCOM Agent Repair Event Logs
Most of all when you repair operations manager agents using any of the above methods, you can use the event viewer to verify the repair operation.
On the client computer check the Application Event Log to confirm it completed successfully or if it had errors while repairing the agent.
When you repair the agent, the first important event ID to look for is 1040. It states Beginning a Windows installer transaction.
Check the next event ID 11728 which confirms the Microsoft Monitoring agent configuration.
Finally check the Event ID 1035 which clearly tells us that Windows Installer reconfigured the product Microsoft Monitoring Agent.
Very Helpful.
