wbemtest not working correctly

Hi,

I've perfomed the following on two machines:

* Start > Run > wbemtest
* Connect > root\CIMV2
* Query: "select * from win32_temperatureprove"

On the one machine, I get two entries which I can check the values of
(though not the actual temperature I want!).

On the other machine, I don't get an error, but no entries are returned.

Any idea what's going on? Perhaps a required service is not running on the
second machine or something like that?

Thanks in advance,
Alain
