I'm using RSTe 22.214.171.1243 on a Intel board with C600+/C220+ controller with Windows Server 2012 Standard.
I'm getting system events from source "iaStorA" with event IDs 4097 and 4098.
There is a message, that a "gebietsschemaspezifische" resource for this message is not available.
But what are the messages about?
We have checked the log files that you attached to the your post and after some research we came to a conclusion that these logs are not from IRSte. These are Microsoft generic RPC admin call issues and this is most likely an admin access to DCOM config.
