Disable prevent windows log event

I'm using WMI (Windows Management Instrumentation) to try to collect some information from a allot of remote computers. The issue is that every time I try to initiate a connection to a remote computer/resource using:

//IWbemLocator::ConnectServer method (wbemcli.h)
m_pLoc->ConnectServer ....

where

IWbemLocator *m_pLoc;

(You can assume m_pLoc is correctly initialized) , if the remote resource is unavailable, Windows generates a log event in the Windows Event Viewer:

DCOM was unable to communicate with the computer ....using any of the configured protocols; requested by PID .....

The problem is that given a huge number of remotes that at some point are not accessible the logs get flooded.

Is there any way to control or to prevent Windows from pushing a event in the Event Viewer every time I try to initiate a connection? Seems that arguments for :

IWbemLocator::ConnectServer method (wbemcli.h)

or CoCreateInstance used to intialize an IWbemLocator do not permit this sort of very custom configuration I'm looking for. Any suggestion or alternatives? Thank you!

Looking at the message logged in EventViewer more closely, I can see that this is a DCOM thing, and it looks like you can turn DCOM error logging off by (as usual) tweaking the registry.

The key you want is:

HKEY_LOCAL_MACHINE
    SOFTWARE
        Microsoft
            Ole

And then create a DWORD value in there called ActivationFailureLoggingLevel and set it to 2.

Info gleaned from here. I haven't tested this myself but it looks like it should work.
