Hi there!
I ran in to the same problem. Could not run it in cmd-window on the client machine either.
The syntax i s correct WMIC /namespace:\\root\ccm path sms_client CALL TriggerSchedule “{00000000-0000-0000-0000-000000000113}” /NOINTERACTIVE
BUT you have to type "
I also had copied the string from some forum. The quotation marks is invalid.
The correct string is WMIC /namespace:\\root\ccm path sms_client CALL TriggerSchedule "{00000000-0000-0000-0000-000000000113}" /NOINTERACTIVE
Now software update is running like a Dream.
