Hi Dan,
Could be. But there definitely should be something in the log reflecting
the event, unless you've configured some rules to not log certain
connections.

Does anyone have an answer on this other than laughter?

I get an lot of these alerts on my ISA2004 server:
ISA Server detected an all port scan attack from Internet Protocol (IP)
address xx.xx.xx.xx.
Normally, I just ignore these, as there isn't much I can do about
outside servers. However, I've noticed a few of these with IP addresses
on our internal network, which has me concerned. Whenever I see one of
these, I check every log I can think of, and don't find any other
indication of any activity other than the alert itself. Even the
Firewall Log doesn't show any blocked packets during that time period.
Do you think the IP address of the scanner is being spoofed?
