zenworksb,

You can run tracert on the IP.  The computer name will appear at the top.  For example ...

tracert 192.168.1.100

Let me know if you have any questions or need more information.

The result will be something like this ...

Tracing router to COMPUTERNAME [192.168.1.100]
(rest of the results)

You can hit Ctrl + C to quit the trace if you wish.

If there is no DNS then ping -a and/or tracert would not work, so (1) SNMP analysis might tell you something about it

Try solarwinds EE edition free trial (www.solarwinds.net)

Use default of 'public' for SNMP sweep.

If this doesn't work, try solarwinds port sweep.  See what ports are open.  If 80 is open, view the IP in a web page.

If this doesn't work, use solarwinds switchport scanner.  Get MAC address, use MAC address to look up manufacturer (might narrow it a bit)

MAC address lookup (http://coffer.com/mac_find/)

Last this might be Nessus (www.nessus.org) to determine OS

None of these are 100% but you should have a lot more information.

If they are internal MS workstations, you can use the  nbtstat -A  ipaddress    command, that will give you the name of the machine.

Try using a network discovery/mgmt tools.  There are some free ones out there that may do the job.

A tiny little utility called TCP Net View should list the IP, Host name and MAC address for you.

Go to control panel - network connections - Double click the LAN adapter that you are using to connect to your local LAN - Click properties - Highlight Internet Protocol (TCP/IP) - Click Properties - Click advanced - Click WINS tab - Under NetBIOS setting select Enable NetBIOS over TCP/IP - Save changes - Restart.

Perform this operation on 2 of your machines (to test).
Go to start menu - run - type cmd and hit ok - type nbtstat -a 10.x.x.x (IP of the other NetBIOS enabled machine).  This should return the machine name.

Then enable NetBIOS on all machines.

Try AngryIP Scanner
http://www.angryziber.com/ipscan/

If the IP's resolve with a local DNS, then the dns names will be shown. NetBIOS names will also be shown..

Else, use Solarwinds IP Network Browser. Get a 30day eval of the toolset

if its only internal names/addresses you are after try the angry IP scanner is good but LANSPY is better for details -

http://lantricks.com/lanspy/.
 
LANSPY does the same as the Angry IP Scanner but in a lot more depth (shows running services on the PC and networked drives etc).
not bad at all for a freebie

If it is an internal IP address, you can check on your DNS server.  You can also use ping -a IP ADDRESS.  This site will do a reverse DNS lookup on public IPs http://remote.12dt.com.  It will resolve and show you who the top level domain is.
