check with non domain admin user on dc

[kuchi]

Hi!

I am new but I have a rather difficult question:
I am making a service check on the domain controller.
Since I have created a user which is not domain admin I am now not able to query the wmi service list, because of insufficient privileges.
Can anyone tell me which permissions I need to enable on a domaincontroller so that the monitor is able to query it.
I have checked so many things already and I enabled to all WMI stores the user via the wmimgmt.msc

Thanx a lot for every help
