wmic : un secret bien gardé

Cela fait maintenant un petit moment que travaille sous Windows, et je viens à peine
de découvrir cet outil surpuissant.Je vous engage à vous y intéresser.

Voici par exemple comment ouvrir une console 'cmd' sur un hôte distant

C:\Documents and Settings\artyprog>wmic /node:192.168.12.1 process call create 'cmd.exe'

Je vous laisse découvrir le reste :-)
