Several customers have reported that the System Center 2012 Endpoint Protection (SCEP) client stops reporting any status to System Center 2012 Configuration Manager sites when the following update is installed on Windows 8.1 clients:
KB3025417 March 2015 antimalware platform update for Windows Defender in Windows 8.1 and Windows...
Clients will record errors that resemble the following in the ExternalEventAgent.log file.
WMI callback for machine notification (SELECT * FROM __InstanceOperationEvent WITHIN 30 WHERE TargetInstance ISA "MSFT_MpComputerStatus") in scope (\.rootMicrosoftProtectionManagement) for group 'EndpointProtection' is not registered.
Failed to get the wmi query result for error = 80041055
To prevent this issue from continuing we have revised the detection logic for KB3025417; as of Friday June 12, 2015 it is no longer offered to clients that are also running System Center Endpoint Protection.
Uninstalling KB3025417 from affected computers, followed by reinstalling the SCEP client, resolves the reporting issue. As an alternative to uninstalling the update, run the following command on the client to restore reporting functionality. Restart the computer afterward for the provider change to take effect.
Register-CimProvider.exe -ProviderName ProtectionManagement -Namespace rootmicrosoftProtectionManagement -Path "C:Program FilesMicrosoft Security ClientProtectionMgmt.dll" -Impersonation True -HostingModel LocalServiceHost -SupportWQL -ForceUpdate
This interoperability issue between Windows Defender and System Center Endpoint Protection will be resolved in future platform updates for Windows Defender.
