If the repository is fine but data is still not found, the Win32_OperatingSystem provider might not be registered correctly. Open Command Prompt as Administrator. Navigate to the WMI folder: cd %windir%\system32\wbem Use code with caution. Re-register the CIM providers:
This isn't just a "file not found" error; it means the OMI service on the collector side successfully reached out but either couldn't access the WMI repository or the repository itself is unresponsive. Common Root Causes Network & Connectivity
If this fails, the issue is likely network-related or credential-based rather than a FortiSIEM GUI bug.
Use ping and telnet to verify that the monitoring collector can reach the target host. 2. Check User Credentials and Permissions win32operatingsystem result not found via omi new
The error message typically indicates a communication or authentication failure between a monitoring collector (like FortiSIEM) and a target Windows host using the Open Management Infrastructure (OMI) protocol. This is not a failure of the class itself, but rather a sign that the OMI client cannot successfully query the target's WMI repository. Common Root Causes
OMI communicates with Windows using standard remote management protocols. Ensure that your hardware firewalls and local Windows Defender Firewalls permit traffic across these critical ports: : RPC Endpoint Mapper UDP Port 137 : NetBIOS Name Service TCP Port 5985 : WS-Management HTTP (Default OMI port) TCP Port 5986 : WS-Management HTTPS
Occasionally, the fault lies entirely within the target Windows machine. If the internal Windows Management Instrumentation repository becomes unstable or drops its registration schemas, remote queries for standard classes like Win32_OperatingSystem return empty objects. 📋 Comprehensive Troubleshooting Workflow If the repository is fine but data is
This often resolves temporary WMI provider deadlocks.
The Remote Test (Execute from the SIEM Collector/Linux Terminal)
Before diving into troubleshooting, it's essential to understand the components involved in the error message. Re-register the CIM providers: This isn't just a
When you see "Result not found via OMI," the Linux collector successfully used OMI protocols to speak to the Windows machine, but the Windows endpoint failed to return the requested WMI class instance. 2. Root Causes of the Error
The user account provided must have remote management rights. Standard fixes include adding the user to the local Administrators' Group on the client host or ensuring Domain Admins have the necessary rights.
