I hadn't seen this behavior before... every 5 minutes, starting at 12:57PM 
EDT, a host at e0.filt2.knox.tn.ena.net is performing the probe...

12:57:01 -0400
13:01:56 -0400
13:06:53 -0400
13:11:50 -0400
13:16:47 -0400

and now it's stopped.

In every previous case, a host has hit the machine I'm looking at one time 
and then never been heard from again.

The possibility exists that this is a firewall of some sort, and multiple 
machines behind it are probing....

Or possibly multiple instances of CodeRed are running on this machine...

These two possibilities seem most likely... but it does bring this 
interesting thought to mind... has a variant been introduced that tries for 
half an hour to probe the same host?
