ExpertExpertIt seems to be a problem with only some WMI classes. I found a server currently showing NO DATA for the SystemUptime thing. When I go on it and check some WMI stuff I get different results.
As you can see below, one WMI call works fine and another does not. When I do a Poll Now on the System Uptime check, it apparently uses the second one which is why it's failing.
Once I run through the LM WMI fixer steps, then both commands start working. Now I'm wondering why some WMIs woudl work and other would not. I guess I need to change my checker script to use the one that SystemUptime uses since CPU checks also use that one.
ProfessorIf the Fixer guide helped, it is most likely broken counters. So it couldn't return data. Which would lead to invalid class. This happens on Windows from time to time, because, well it is Windows.
