how to find mac addresses?

[FN-GM]

This might be a silly question. How can I find out Mac addresses of machines remotely & how would I find them in windows?

 

Thanks

From a command line.

 

Ipconfig /all

 

Check the physical address path. [ for local ]

 

nbtstat -a [ IP ADDRESS ] should return the mac address if the device is on.

[ For a remote ]

cheers mate!

The nbtstat command will return a remote mac address on a PC. Not sure on a printer though....

 

Most IP printers will have a web interface of management console in which the MAC address should be present.

 

There may be another command, but this is what I use.

The MACs will also be listed in your DHCP Lease from your server.

If you use GHOST, the console shows MAC addresses.....

 

More than one way to skin a car as they say.........

If you know its IP ping it. Then from cmd, arp -a

 

DHCP will also tell you.

Were about in the DHCP in Windows Server 2003 please i can't find it?

Under leases it will be under one of the columns.

The DHCP log server files will also tell you.

ARPWatch is also a handy tool http://freshmeat.net/projects/arpwatch-ng/

If you want a command line tool then dhcpcmd (resource kit) works -

 

dhcpcmd 10.128.0.1 enumclients 10.128.0.0 -h

 

will query the server at 10.128.0.1 and return the hardware info (ie including mac address!) for the leases at 10.128.0.0

"Angry IP scanner" will let you scan an IP range and gives you the name of the PCs and there MAC addresses (I think you have to chage a setting before it shows the MAC).
