Under the "Prefs." tab I am removing the check from "Do a TCP ping" and
there is no check in "Do an ICMP ping" .. 

Under NMAP options "Ping the remote host" was not checked. 

My targets still show up as dead almost immediately!  A port scan is not
being performed.  The Nessus message is "The remote host is considered
as dead - not scanning."

These targets are running ZoneAlarm on W2K boxes.

Any ideas?  TCP Ping to a specific port is not an option because none of
the machines are running consistent services.

Thanks!

Mark

You need to make sure you have the "ping host" option disabled in both
the
NMAP options and the nessus scanning preferences.  The drawback is that
it
will take much longer, especially if scanning a range of IP's that have
many
non-active IP's in it.  This is because most personal firewalls block
Ping
requests.  The other option would be to set nessus to do a "TCP" ping,
and
configure it to a port that all the machines have running.

Subject: Scanning targets with personal firewalls running?

I was playing with Nessus (default options, except scanning 65535 ports)
and noticed that my machines running personal firewalls came back as
dead.  I'm not extremely familiar with nmap, which I'm assuming is the
component I need to tweak to force a "full" scan on these targets.

Any advice on how to configure Nessus to scan targets running personal
firewalls?  As an example, I have one box that only has a single inbound
port open, running a Return to Castle Wolfenstein Server.  Running
Nessus w/ default options shows this to me as a dead box.

Thanks for the help!

Mark
