An error similar to the following will be displayed in the VMM Admin Console:
The Windows Remote Management (WS-Management) service cannot process the request. The object was not found on the server (host.contoso.com).
WinRM: URL: [http://host.contoso.com:5985], Verb: [GET], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/virtualization/v2/Msvm_VirtualSystemSettingData?InstanceID=Microsoft:73F1C285-7765-48F9-9472-9984B3B60336]
Unknown error (0x80338000)
Ensure that the VMM agent is installed and running. If the error persists, restart the virtualization server (PRDTDC-HVS001.cgli.int) and then try the operation again.
1. Open an elevated Command Prompt by right-clicking on the shortcut to Command Prompt and choosing Run As Administrator on the host computer.
2. Use the CD command to navigate to the %windir%\System32\Wbem directory.
3. Run the following command:
for /f %x in ('dir /b *.mof ^| findstr /v /i uninstall') do mofcomp %x
These steps rebuild the WMI repository on the host. After the next host update in Virtual Machine Manager, the hosts should report that they are in the Ready state.
