In this instance I was the user and I went to that PC logged on.  I went
to 5 different websites, www.msn.com, www.yahoo.com, www.google.com,
www.cnn.com, and www.microsoft.com.  I then didn't a query to pull up
all requests from that IP address in the webproxy log.  Every request
was too an IP address not a FQDN.  I am in transition mode in my
installation now and my default gateway does not point to my ISA server,
(before you scream at me in the end it will be, currently testing a
subset of users with proxy settings and firewall client software), so
securenat request could not be routed to the ISA server.

It's a little confusing to me why one machine would be acting this way.
If you try to go to most of the URLs they do not even function with the
IP instead of the FQDN because the side must look at host headers.

Maybe the request was made to an address, or the client is acting in the
role of SecureNAT client for that connection.
