RE: bug w2k

["Vladimir Kraljevic" <vladimir_kraljevic () llbudapest hu>]

It works with the simulated keystrokes as well... I was able to track it
down up to the point where subsystem crashes, but I have no more time to
spend on it.

I was able to get access violation system box and delay the restart;
everyone with decent kernel debugger (SoftICE and kinds) can trace the exact
point of the crash. I'm pretty sure that you are getting system account. If
I'm right, we'll soon have nice exploit, usefull to anyone that has access
to the CLI.

Enough for now, some work will follow, have some ideas

P.S. You can repeat last two lines (SendInput(...))
