Hi Shane. Do you have Nessus configured to ping the remote host(s)? When you run nmap manually are you passing it the "-P0" flag? Do these skipped hosts respond to regular ICMP pings? If you have Nessus configured to ping the remote host (ICMP), and the host does not respond to ICMP, Nessus will automatically 'skip' that host. ~Jay -- .. .. Jay Jacobson ..
