EventLog Permission Difference between 2016 and 2019

Hi there,

We have a legacy application that is trying to create an event source and tries to write event logs in a separately created EventLog. I tried to assign the permissions according to the following article:
https://support.microsoft.com/de-ch/help/323076/how-to-set-event-log-security-locally-or-by-using-group-policy

It works in Windows Server 2016, but not for Windows Server 2019. According to my network trace the server replies with [Expert Info (Note/Response): Fault: nca_s_fault_ndr].

I am kind of stuck here. Do you have any suggestions how I can continue my troubleshooting here?

Thanks,
O
