Active Directory WMI query runs CPU to 100%



Platform: PRTG Network Monitor 14 Active Directory Server based on Microsoft Windows 2003 o 2008 r2, en 32 o 64 bits All servers are based on virtual platform VMWare ESXI 5.1 update 2. Polling interval: 60 seconds

We query servers using WMI and CPU rises to 100%, and need to be restarted.

We need to know if its a PRTG problem or a WMI problem, or something else.

on which machine do you see the high CPU usage? On the machine running PRTG? On your domain controller? On normal target machines?

best regards.

The virtual Domain Controler (Windows Server 2008) running on VMWare ESXI 5.1 is the machine thats runs out of CPU. When queried by WMI CPU rises to 100%

PRTG Server is running perfect
