OP System 0 Posted June 16, 2021 Share Posted June 16, 2021 Hello all, resuming from this comment by Nightowl we're still observing thousands WmiPrvSE.exe blocked operations by HIPS in all our MS 2012 Servers (see attachment). Yes I know, “Log all blocked operations” option can be disabled, but I’m wondering if all these events could impact system performance / stability somehow… why does this happen on 2012 (R2) only and not in subsequent versions? Thanks Gabriele Link to comment Share on other sites More sharing options...

It's a question for Microsoft, the maker of the OS and the file in question. As you have correctly pointed out, logging of blocked operations should be disabled unless troubleshooting a HIPS related issue. Link to comment Share on other sites More sharing options...
OP System 0 Posted June 16, 2021 Author Share Posted June 16, 2021 Thanks Marcos, Just for sake of knowledge, do you know why those operations get blocked or why on 2012 specifically? Maybe someone else already got through WMI tracing in the past… Link to comment Share on other sites More sharing options...

Maybe someone else already got through WMI tracing in the past… Previously observing what Eset HIPS internal rules due at boot time, it will only block specific process activity rather than all activity from a process. Your screen shot is in Italian so I can't determine what specific WmiPrvSE.exe activity is being blocked. But I have seen the same activity on Win 10 builds and it is not affecting any WmiPrvSE.exe functionality that I am aware of. Link to comment Share on other sites More sharing options...
