If anyone is able to test this, please do report your results!  As
we've been pretty rushed since we just found out about the technique
yesterday.


Ran it across our desktop network here.

bash-3.2# nmap --script=smb-check-vulns --script-args=safe=1 -p445 -d
10.10.1.0/24 |grep Conficker

I assume the NT_STATUS_OBJECT_NAME_NOT_FOUND implies it's not an actual
Windows box?  We do have some Ubuntu / Mac users here...
