Finding computer name from IP

[Sir Rugmuncher]

I have about 15 computers connected together on a LAN, and one of the PC's is the server. Now my question is if I've got an IP address how can I find the name of the computer with that IP address?

Note I have access to the server.

if you know which computer the ip links to then you can probably find out using ipconfig /all

[Sir Rugmuncher]

I'm not sure thats what i want simsie.... I'll rephrase, I'm on the server and have an ip address. How can I know the name of the computer (or username of person on that pc) that is using that IP?

It's easy to find the computer name - go to a command prompt and type nslookup <ip>

There are instances where this won't work but without going into detail as to why, give it a shot. If the server is a Windows domain controller and the client PCs are members of the domain it should work fine since they'll have the domain controller specified as the primary DNS server.

have you tried using the "Net" command in the command prompt.

Although i am not sure which one does it i think one does what you are after (try net /?) although i personally think its net view

if the computer registered with your dns, then yes nslookup will work.. If not are you running dhcp on the server, then look at the leases.

Or you could always just used nbtstat -A ipaddress
