Win2000 System Unexpected Shutdown

[Steve]

After connectecting to my Internet ISP and launching IE
6.0, Win2000 pops up with a System Shutdown message
discussing the fact that c:\winnt\system32\lsass.exe has
terminated.

In searching the KB, I can't find much info (maybe it's me)

What may be happening?

Greetings --

You've apparently contracted the latest worm, W32.Sasser.Worm,
specifically designed to attack people who do not update their
computers promptly and who do not practice "safe hex." In other
words, like Blaster, this worm was developed and distributed _after_ a
patch for the vulnerability was announced and made publicly available.
Further, and also like Blaster, this worm could not affect any
computer whose user had taken the basic precaution of using a properly
configured firewall.

To stay on-line long enough to get the necessary updates, patches,
and removal tools, click Start > Run, and enter "shutdown -a" when the
next Shutdown countdown begins. This will abort the shut down. Also,
make sure you've enabled a firewall before starting, to preclude any
more intrusions while getting the updates/patches/tools.

When trying to perform the function below, I could not get the "shutdown -a"
to do anything besides give a message saying the file was not found. Do I
need to enter that same thing from the command prompt and not from the actual
"Run" line?
