Microsoft Windows Wkssvc NetrJoinDomain2 Stack Overflow(MS06-070) Exploit

by cocoruder(frankruder_at_hotmail.com),2006.11.15
page:http://ruder.cdut.net/default.asp

successfully test on Windows 2000 Server SP4(chinese)

usage:
ms06070 targetip DomainName

notice:
Make sure the DomainName is valid and live,more informations see
http://research.eeye.com/html/advisories/published/AD20061114.html,
cocoruder just research the vulnerability and give the exploit for 
Win2000.
