Well Jeb,
Some people in the industry, higher this dude named bubba to do out
packet sniffing and tracing.
Sam spade does a good job at tracing as well. What you can do is look
up the domain contact
At internic or dotster and then email the host and inform them of
suspicious or possible activity
Coming from that group of ip address.
Thank you,
Joseph

I have been noticing what ISA is calling "port scan attacks" for the
past week or so from the same IP address. I am just getting my feet wet
with trying to monitor security closely and don't mean to sound like a
complete idiot. (Oops! To late?) Does this mean someone is purposely
scanning my ISA server for holes or could it be something non
intentional? Is there really anything that can be done about it? I have
already found out who owns that block of ip addresses provided the
source address is not being spoofed. Does Tom's book cover questions
about what the different log messages mean? Thanks!
Jeb
