Lsass.exe high CPU usage on Windows Server 2016

  • 772

My website runs on Windows Server 2016. It looks as follows:

  • IIS with 3 applications running with SSL:
    • MVC website (.Net Framework 4.7).
    • Two .Net Core 3.1 Api's.
  • MS SQL Express 2019.

If the traffic increases, the CPU for lsass.exe (yellow) increases dramatically:

enter image description here

In the end it takes so much CPU that my own applications get slow. I searched on the internet, most problem solving is linked to MS Active Directory. However, this is not installed on the server.

My question: Does anyone know how to identify which process is causing this behaviour? Is it a virus, MS SQL, SSL??
