from IP to computer name in switch

[Mary]

we want to know which computer name is using IP 10.23.1.21 (thorugh wifi) in switch

Is it possible using some command to detect? I find show user command can list computer name, any similar command we can have computer name giving ip

[Dennis Mink]

from a dos prompt go ping -a  <ip address>  this should do a reverse lookup.

You can use the below mentioned command for getting the hostname of that particular system: 

netstat -a <ip address>

Which Wireless System are you using?

You could look at the DHCP Scope (if using Windows Server) as this may list the hostname against the IP.

we are using lightweight AP, our DHCP is windows 2008, but I can't access server manager in windows 2008, how to see hostnmae against IP in win 2008?
