Eventlog Analyzer WMI query method

Eventlog Analyzer WMI query method

Is there any way to change EventLog Analyzer to make Windows server queries in semisynchronous mode?
We are having troubles to scan devices behind physical firewall, we are getting "RPC server unavailable" error message.

When running Windows Management Instrumentation Tester, semisychronous mode works, but when changing to Asynchronous mode, we get RPC Server unavailable.
It seems that EventLog analyzer uses asynchronous mode for WMI queries, which don't work
