New | Win32operatingsystem Result Not Found Via Omi

The Remote Test (Execute from the SIEM Collector/Linux Terminal)

Manually test the connection using the omic tool from your FortiSIEM node:

Review the Azure Policy assignments for "Guest Configuration" and ensure root\cimv2 and Win32OperatingSystem are not excluded. win32operatingsystem result not found via omi new

The error typically indicates a communication or permission failure between your management platform (such as FortiSIEM) and the target Windows host. Primary Troubleshooting Steps

: Ensure the following ports are open on the Windows host's firewall: TCP/135 : RPC Endpoint Mapper. TCP/5985 (HTTP) or 5986 (HTTPS): WinRM/OMI communication. UDP/137 : NetBIOS Name Service. Advanced Troubleshooting The Remote Test (Execute from the SIEM Collector/Linux

OMI on Windows uses WinRM or DCOM internally to bridge to WMI. If WinRM is disabled or the firewall blocks high-numbered RPC ports, the OMI server cannot complete the request.

export OMI_TRACE_LEVEL=3 omicli enum root/cimv2 Win32OperatingSystem TCP/5985 (HTTP) or 5986 (HTTPS): WinRM/OMI communication

Because there is no installed provider listening for that specific class ID, the OMI agent returns "Not Found" or an empty result set.

The proposed feature aims to enhance the interoperability and usability of OMI by ensuring that critical system information, such as that provided by the Win32_OperatingSystem class, is readily accessible. Implementing this feature would involve a deep dive into OMI's architecture and potentially significant code changes to support the discovery and exposure of WMI classes through OMI.
