If you can't figure out what this button does, then you certainly won't understand what this program is for!
Configuration Screen
Resolve Host Names
Check this box to resolve IP addresses to host names during a scan. Host name resolution is usually the single most time consuming part of a scan, so turn this off if you don't need the host names.
Ping Test
Check this box to perform an ICMP ping test. Ten pings will be performed and the minimum, maximum, and average times will be displayed.
Continue on error
Check this box to continue scanning even if the system does not respond to a ping. Some firewalls will filter out ICMP, so ping will fail, but other tests will succeed.
Windows (SMB) Networking
Check this box to scan for Windows networking shared drives and printers.
Web Server
Check this box to scan for WWW Servers on port numbers 80, 443, 1080, 8000, and 8080.

Click on this button to Un-select all of the scanning tests.
Timeout
The timeout period in seconds, for each socket operation. (Note: this does not apply to the Windows Networking Scan. I have found no way to control the time-out on this operation.)
Maximum Threads
The maximum number of threads the program will use. Each host is scanned simultaneously by a separate thread. Reducing this number will reduce the amount of system resources used during a scan. Increasing it will allow more hosts to be scanned simultaneously, but may cause the system to run out of resources. If the program crashes shortly after starting a scan, reduce this number. My system (NT 4.0 with 64 Mbytes) runs fine with 150 threads.
Maximum Sockets
The maximum number of simultaneous asynchronous sockets to use (per thread) when doing the port range scan. Like threads, more will run faster, but too many will cause the program to fail.
OK
Cancel
If you don't know what these are for, then please turn off your computer now and never touch it again.
