Hey guys, thanks of the posts so far.

I don't want to do a DOS as others do have to use the network and it isn't really my goal. My goal is to get "root" or one of the admin accounts. Sorry should of said that before. I've been keeping the techies informed when I've been doing some test so far so I have that angle covered.

If someone has some idea's of angles of attack or even some pointers as to holes in MS at the moment thats what I really need. I can port steal and collect passwords but they are encrypted and john the ripper is taking forever to crack the passwords I have collected. Anyone know a better tool to use?

Thanks for what's been sugested so far.
