What error do you get when starting collector?
I've run the user-defined active directory diagnostics report and managed to get the below report. The SAM utilizing the maximum CPU and I am not sure which objects are running constantly which are utilizing the CPU, can you please support me how can I normalize the CPU utilization and terminate the unwanted jobs
- Hello! We have the same problem, LSASS.exe loads 90% CPU on some Domain Controllers, in the Perfmon report we observe many requests from the SAM client.
How did you solve your problem?
Thank you
