If you do some checking with Google, you'll find that some people have 
done a number of things on various operating systems when they see these 
kinds of requests come through.

The more interesting (I think) are the ones recognized as the IIS 
codered worm, because if they're knocking on your door it means they're 
already infected, which gives you some more information about the host 
system.

There's a pretty popular script floating around to pop up a notification 
window on the infected host with a warning to the owner that they've 
been infected, along with a handy URL to find out more info.  Others 
noted that it might be a headless box in a closet somewhere, so have 
attempted to modify the script to broadcast a message to the local 
domain/workgroup to let anyone/everyone know that the host is infected.

Some people have attempted to write scripts which go back and kill the 
worm on the infected host.

Here's a random example (Googled):

Please note that exploiting an infected host to notify the owner of its 
infection is probably illegal in the United States and any country 
willing to buy U.S. goods rather than produce them.
