The error indicates that OMI’s internal class provider lookup failed. Possible reasons include:
"failed (Win32_OperatingSystem results not found via OMI)" a common troubleshooting roadblock for IT administrators, particularly those using to discover and monitor Windows hosts
To help isolate your specific setup, what (e.g., FortiSIEM) are you deploying? Sharing the Windows Server version you are targeting can also pinpoint potential configuration mismatches. Share public link
However, if you strictly require Win32_OperatingSystem for compatibility with a legacy tool, you may need to verify that the provider you installed specifically aliases its output to that class name.

When OMI queries the Win32_OperatingSystem class via the OMI provider, it expects structured data. If the query returns empty, the "result not found" message is triggered. Common Causes for the Error
if __name__ == "__main__": get_os_info()
If the network and credentials are correct but the class remains "not found," the WMI repository on the Windows host may be inconsistent. Microsoft Community Hub Check Consistency: winmgmt /verifyrepository in an elevated Command Prompt. If inconsistent, run winmgmt /salvagerepository . For severe issues, winmgmt /resetrepository may be required to return WMI to its default state. Microsoft Learn Diagnostic CLI Test
A lightweight, open-source CIM management server frequently used on Linux agents and gateway servers.
When OMI on Linux uses WinRM (WS-Management) to talk to a Windows machine, it authenticates via Kerberos or Basic Auth. However, when OMI uses the older DCOM protocol (less common in modern builds), the Windows firewall and DCOM permissions can block access.
