For those of you who don't regularly read Help Net, I recommend that you surf on over and take a look at the PDF "Introduction to the Windows Management Instrumentation Command-line (WMIC)" written by friend and colleague Bill Lynch. Check out the introduction:
It’s quite possible you’ve never heard of the Windows Management Instrumentation Command-line (WMIC), but this well kept secret command-line tool is immensely powerful for gathering information from Windows-based systems. Because it can be used both locally and over the network and is installed by default on most Windows-based systems since Windows 2000, it’s exceedingly useful for both penetration testing and forensics tasks.
Nice, right? Anyway, I highly recommend checking it out; WMI is pretty cool, and who knows what kind of trouble you can get into by using it from the command line. ;-)
