Windows 2000 and Windows NT 4.0 source code leaked

Everyone’s turn comes eventually… The source code for Windows 2000 and Windows NT 4.0
 appeared illegally on the internet. I imagine it caused quite a stir in Redmond. The official statement 
 shows that it wasn’t a hoax: Statement from Microsoft Regarding Illegal Posting of Windows Source Code.
 And they say Microsoft never understood open source (news via ienik).
