I had a similar issue some time back.
Enable ICMP ping. Check your nessus logs because it might be the nessus
scanner is reporting these hosts as dead which means it doesn't even see
them on the network.
Enable ICMP ping. If it fails than... I don't know and I'll let the
more advance guys tell ya lol..

Hi Guys,
Is there an FAQ for how to deal with Firewalls, - it seems to me
that
alot of people have trouble with this issue.
I am getting back no test results for scanning XP machines with the SP2
service pack firewall enabled. The scan completes in seconds but comes
back with a 'there are no results to view for this' message
Scanning the mailing list I can confirm that I have disabled pinging the
remote host, the SMB credentials are correct. I am using the Nessus TCP
scanner.
I tried to use Nmap scanner with the option for fragment IP packets but
this made no difference.
I understand that firewalls make things very difficult, but thought Id
post before banging my head against the wall and giving up on firewalled
machines.
Also regarding best practice for XP, on a windows 2000 box, a complete
(1-65535) port scan using TCP scanner and all the windows family plugins
enabled takes about 7-10 mins depending on time of day.
In XP, with the same settings, I am averaging two hours or more per
host, is this normal? Searching for slow XP scans hasn't brought up
anything that I can see to help...
Im happy to upload a report with the config options if that would help
with the diagnosis...
Many thanks
Martin
