This error typically appears in monitoring platforms like FortiSIEM when trying to discover or communicate with a Windows host via the . It indicates that while a connection may have been initiated, the specific WMI class responsible for returning operating system details ( Win32_OperatingSystem ) could not be retrieved. Common Causes win32operatingsystem result not found via omi new
This specific failure prevents remote platforms from gathering basic system details like the hostname, operating system version, and patch levels. Resolving it requires diagnosing permissions, network layers, and the underlying Windows Management Instrumentation (WMI) subsystem. Understanding the Architecture: OMI vs. WMI This is usually caused by authentication failures, missing
integration with Windows hosts when the Open Management Infrastructure (OMI) client cannot retrieve basic system information. This is usually caused by authentication failures, missing permissions, or misconfigured network listeners. Common Causes & Solutions Authentication Method Misconfiguration Switching from Kerberos-auth Resolving it requires diagnosing permissions
OMI communication requires specific ports to be open. Ensure the following are not blocked by firewalls: TCP/135 and UDP/137 (RPC/NetBIOS). TCP/5985 (HTTP) and TCP/5986 (HTTPS) for WinRM/OMI.
