Many ISP providers uses your ethernet card (lan card) mac address to recognize your system and assign unique Ip address in that lan.
If you have multiple system or to use any guests laptop's it is very difficult to contact ISP customer care to register the new Mac address.
So we can set the mac id of our system which is already registered with ISP in the guests system. This is called cloning of mac.
First we need to get the mac id of our primary system:
1. Open Cmd prompt
2. Type the command getmac and then enter will give us the mac address.
3. Copy the physical address(we will call this as mac address) in note pad .
In this screen shot 08-00-27-C0-EB-AA.
Thats it our fist step completed
To change the mac address in target system.
1. Right click on network icon in system tray(near time and date)
2. select status
3. Click on properties.
4. Local area network properties dialog opens up.
5. Click on configure button.
6. From the openned dialog box select advanced tab.
7. Select Network address option from the list menu.
8. Click on value radio button.
9. Enter the mac address we have saved from the source system. In this it is.
080027C0EBAA.***Enter mac address with out '-'.
10. Click on ok button.
11. Restart the system.
12. Check the mac id with the "getmac" command from command prompt. We did this in first phase to collect the mac id from source.
Thats it we are done.
