Answer 1

As Daren Thomas said, use nmap.

 nmap -sP 192.168.1.1/24

to scan the network 192.168.1.*

 nmap -O 192.168.1.1/24

to get the operating system of the user. For more information, read the manpage

 man nmap

Answer 2

If you're using DHCP then the server will give you a list of all that information.

This website has a good tutorial on using powershell to get networking information http://www.powershellpro.com/powershell-tutorial-introduction/powershell-scripting-with-wmi/

If you neet to get quick list of computer names you can use "net view". Also have a look at nbmac although I'm unsure of it's working status under XP. Another option could be to use nbtstat -a (once you've used net view to list workstations)

Answer 3

In PowerShell you can do something like:

$computers = "server1","server2","server3"

Get-WmiObject Win32_NetworkAdapterConfiguration -computer $computers -filter "IPEnabled ='true'" | select __Server,IPAddress,MACAddress

Answer 4

arp -a

That gets everything the current machine knows about on the network.

(I'm putting this up there as a second option, since nmap isn't universally installed).

Answer 5

In PowerShell:

function Explore-Net($subnet, [int[]]$range){
    $range | % { test-connection "$subnet.$_" -count 1 -erroraction silentlycontinue} | select -Property address | % {[net.dns]::gethostbyaddress($_.address)}
}

Example:

Explore-Net 192.168.2 @(3..10)
