On the target Windows machine, go to Security > Windows Firewall > Change Settings and ensure the Windows Management Instrumentation (WMI) exception is enabled. 3. Repair a Corrupted WMI Repository
Ensure your OMI client is using the correct port and encryption. For example, if you are using omicli to test the connection, verify you are targeting the correct port (typically 5985 for HTTP or 5986 for HTTPS). 2.

If the OMI client cannot reach the WMI/CIM service, it will return an empty result or a timeout error. On the target Windows machine, go to Security
Ensure that RPC/WMI ports (TCP 135 and the dynamic range 49152-65535) are open between the collector and the target. For example, if you are using omicli to
The most common reason for "result not found" via OMI is an issue with how the collector authenticates with the target Windows server.
This guide breaks down the common causes—ranging from authentication mismatches to corrupted WMI repositories—and how to resolve them. 1. Resolve Authentication and Protocol Mismatches
