You seem to have completely missed the point even though MadHat

eeyerulez.asp performs a buffer overflow that results in SYSTEM level
access to the server.  The question you must ask is do you want to be a
luser on the system or do you want to 0wn it?

Hi,

 IIS runs as SYSTEM user by default. I belive you gain SYSTEM level
access, when starting an ncx.exe for example. With system privilege you
really own the computer. You can do anything with that box, but nothing
with the network. Of course you can switch to some domain user, which is
more powerfull in the network.
