Installation of SCOM Agent 2012 SP1 or R2 via Windows Update Fail
The monitoring agent’s update of the System Center Operations Manager SP1 and R2 can cause some errors when being installed, even for Windows Update in Windows Server 2008 R2 and Windows Server 2012 in some cases.
The problem usually happens on APM installation, a component used to make monitoring of applications in IIS, best known for bringing the performance of queries and pages into Java and .NET.
If the install Windows update and check for the error in the Event Viewer to find the error below, the APM is in trouble:
Product: Microsoft Monitoring Agent–Error 1923. Service ‘ @ C:\Program Files\Microsoft Monitoring Agent\Agent\APMDOTNETAgent\InterceptSvc.exe, -100 ‘ (System Center Management APM) could not be installed. Verify that you have sufficient privileges to install system services.
Many problems may have caused this error, in some cases it may even be necessary to reinstall IIS.
However, as the Application Monitoring feature is used in very specific cases and many times this error happens in different servers, for example, System Center, Exchange servers or others we will not monitor the application, there’s no need to debug the error in detail.
Find the Windows directory Update (C:\Windows\SoftwareDistribution) agent’s file, which in version R2 UR2 is the KB2929891-AMD64-Agent.msp:
Run the following command to install the agent manually using the MSIEXEC without the option of the APM agent:
msiexec /update KB2929891-AMD64-Agent.msp NOAPM=1
Important: The recommended is to really solve the problem because other updates may generate error again. But for this you must use the MSIEXEC LOG and check the components that are in trouble.
