I found this nice tool to scan your LAN

This handy little executable is a bit large since it’s written in Ruby. Simply put, it opens a command prompt window and scans your LAN. It then displays all computers on your Windows workgroup along with their IP addresses, MAC addresses, and which computer in the workgroup is the Master Browser. No more tedious command-prompting to figure out which machine isn’t doing its job as the Master Browser!

 

- Tested on Windows XP, XP x64, Vista, and Windows 7 x64 -

I like this one: http://www.radmin.com/products/utilities/ipscanner.php

One scanner is better than all others

My scanner can beat up your scanner: http://www.remote-exploit.org/backtrack.html

lol thats because yours is a distro.

 

Which just as an fyi i use every day of my life

btw... don't run nikto or paros against unraid... it kills it.

I know it was cheating, but I know what nmap and backtrack are - I have no idea what these other tools are or what they could do to my systems.
