Nobody, will gracefully except a few $ for a pint this evening ;

     If you use passive mode to acquire WMI data, you must sufficiently
debate your freshness
settings for the passive service defined, and or in this case negate wether
you will, per default, go into
a fault mode ,when nothing is received and the freshness timer is expired.

Otherwise you get in the situation, you describe.
