omi new root/cimv2 Win32_OperatingSystem If the error persists despite all fixes, consider these alternatives: 1. Query via WinRM Instead of OMI Use PowerShell remoting directly:

# Correct form (namespace class) omi new root/cimv2 Win32_OperatingSystem omi new --namespace root/cimv2 Win32_OperatingSystem

: OMI’s default namespace mapping is misconfigured.

If you continue to encounter the issue after exhausting the steps above, consider opening an issue on the Open Group’s OMI GitHub repository with your omi.log and the output of omiserver –version . : win32operatingsystem result not found via omi new, OMI troubleshooting, Win32_OperatingSystem empty result, OMI new fails, WMI class not found OMI, fix OMI Windows query.

: On the Windows target, run as Administrator:

# Stop WMI service net stop winmgmt /y ren %windir%\System32\wbem\Repository Repository_old Restart WMI (it rebuilds the repository) net start winmgmt Re-register all WMI classes cd %windir%\System32\wbem for /f %s in ('dir /b *.mof') do mofcomp %s

By systematically isolating the issue—testing local WMI, checking OMI logs, validating namespaces, and adjusting permissions—you can resolve the error and restore reliable cross-platform OS inventory. Once fixed, OMI becomes a powerful, lightweight alternative to full WinRM or SSH for managing heterogeneous environments.

: Always explicitly specify the namespace:
