Identifying PC on LAN

[anarchist]

how we can identify a PC on LAN?

IP address, computer name can be changed easily (in static IP address system). MAC address of NIC card can be changed. is there any thing which can not be changed by the user, and may be used for identification?

You can change the LAN card and so the MAC address, but what if it's an onboard LAN. MAC address is still your best bet.

how to change machine id

We can change the MAC address of a lan card
If you use a lancard with realtek drivers or D-link, then follow the method below directly
Open the Control Panel and navigate to Network connections.
Double click the Broad Band connection which you use to connect
Click Properties. You find your Lancard there under "Connect Using".
Click Configure and Go to Advanced Where you find some of the properties like "Recieve Buffer", "Incoming Buffer" etcc..
There You find a property called "Network Address" or "Network Identifier" (Based on the Lancard company) and its default value is set to Not Present. You also find a box above. Type the desired Machine address there... Ok and then you are done.
