  1. Prefer omi query or omi enumerate – Never use omi new for data retrieval.
  2. Use the standard CIM_OperatingSystem class – It works across Windows and Linux OMI endpoints.
  3. Run OMI in WinRM mode – Disable DCOM by setting dcom_enabled = false in omiserver.conf.
  4. Regularly audit WMI permissions – Use Set-WmiNamespace -Namespace root\cimv2 -Account "OMI_Account" -Permission "Remote Enable".
  5. Log OMI queries – Enable verbose logging on both client and server for rapid debugging.
  6. Stay updated – OMI versions prior to 1.6.8 have known issues with class enumeration over HTTP/HTTPS.
