Shutting down windows NT remotely (without winnt toolkit)?

A reboot isn't helpful coz the machines come back up and start scanning the
whole internet again. And the clueless admins probably won't even notice.

A proper no data loss shutdown without having to upload a program is
preferable. I tried shutting down NT 4.0 using cmd.exe, rundll32.exe and
user32.dll stuff and no luck so far :(. 

With a shutdown the admins should notice and eventually fix things. If they
don't then the server probably wasn't doing anything useful (just scanning
the internet :) ) so it might as well be shut down :).

Any ideas welcome.

Cheerio,
Link.

I haven't continued virii-esque development past NT4 SP6, but I imagine the
techniques would still work as well as pass right through any monitoring
agent. I have a lot of free time these days so I might see what I can cook
up for 2000/XP.

Is it possible to use it shutdown those Code Red/Nimda NT servers
remotely?
Does IIS by default have enough permissions to shutdown the whole computer
or must it do some set privilege thing?

Cheerio,
