Looking for a tool to run on network that will show all devices and information about them

I am trying to find a free tool that will scan a network and give me information about all devices found. Maybe even give me a diagram of what is out there. I am looking for something free...

yes it is a windows network
All of the utilities I listed have Windows variants, but some of them come in other flavors (Unix, Mac, Linux, etc) as well. What kind of information are you trying to retrieve?
Basicly looking for what kind of device it is, name of computer and the OS.
Nmap / Zenmap uses the open ports (among other things) to try and determine OS and device type. Additionally, if a DNS name is configured, and if DNS is configured properly in your environment, it will give you the name of the device. Often times OS detection will lead directly to the type of device - An object running Cisco IOS is not going to be a printer or desktop. ;) Again, this is an extremely powerful tool, and there is a lot of documentation on it.

If you spend the time to configure this correctly and get familiar with the documentation, you will be rewarded with a tool that is useful in a multitude of scenarios.
I did this myself not too long ago and did some hunting for a tool that would work properly.  After trying 5+ different software packages I ended up manually checking each machine.  While this did take some time I was able to know exactly what is on my network and where.  I was also able to run a system information tool that I could then take back with me in order to build up my database of hardware.  

One of the big things that I found is that a lot of the products out there use ping, SNMP, and possibly WMI to try to get information.  Now depending on the device it may not get a response if the firewall is turned on, snmp is disabled, or if there is no guest access turned on.  

Once tool that I did use and probably liked the best from the free software was by Softperfect.  Pretty straightforward and easy to use.  http://www.softperfect.com/products/networkscanner/
