My environment, a physical server desktop. In this physical server I have the HyperV installed and with two VMs running on Windows domain.

In both virutuais machines WMI works normally, but on the physical host that is in workgroup WMI does not work. SNMP functions normally, but most of the monitors that are necessary WMI.

I signed the credential, released on the firewall, telnet test and the doors are open. WMI service is executing.

In the test in OpManager appears fault message, but does not appear the reason. What can it be?

Some other test?
