voice. Thank you.)

Hey kids! Did you ever want to have your very own IIS server? Well
now you can! Just turn on your handy little Zone Alarm firewall and
sit back and relax. Before you know it, you'll be overflowing with
all the FREE systems you could want. Once you find a few hundred you
like, just telnet to port 80 and show the following "GET in FREE"
command:

GET /scripts/root.exe HTTP/1.0.

It's just....that....easy! Have you ever had a deal this good! 
What's even better is that this isn't just for a limited time, just
wait till next month and the deal starts all over again. So head
down to your nearest listserve and pick up your IIS server now!
Remember it's all FREE!!!

The NEW and IMPROVED worm installs a Telnet server which you can
access with the a simple HTTP Get request.

Simply collect some "hits" with your favorite firewall log, and you
have the IPs of "open" IIS servers. If you then telnet to port 80 at
that IP, and give the command above, you receive a system prompt.
