UF - WinEventLog Security collection error - GUID translation failure

[olivier_guisneu]

Hi,

We deployed an UF on a Win server 2022 and enabled the [WinEventLog://Security] log collection. 

The log collection stops for hours sometime, and we see this error :

ERROR ExecProcessor [6468 ExecProcessor] - message from ""C:\Program Files\SplunkUniversalForwarder\bin\splunk-winevtlog.exe"" WinEventCommonChannel - WinEventLogChannelBase::transADObject: Failed to convert guid string to guid structure: Invalid class string

After a few hours or minutes (randomly), Splunk starts again the log collection and then stops again. And all of that witout any service restart.

It only happens with Security Event logs. No issue with Application or System.

Has anyone seen this error before?

Splunk UF version : 9.0.5 (64bits)
Splunk_TA_windows : 8.7.0

I'm having the same exact error on Server 2022, except with UF v9.1.3.

@olivier_guisneu  Did you reach out to splunk support? I am facing similar issue.

We upgraded the UF to v 9.0.6 and it solved our issue

@olivier_guisneu - I don't see that as a Known issue with Splunk. If you have Splunk license, you can raise a Splunk support case for this.

I hope this helps!! Consider upvoting!!
