There are Many applications in which license keys are based on the MAC address of the Server. This can be easily achievable in Physical servers. MAC won’t change frequently until there is no change with the server hardware.Achieving this in virtual Machine is bit tricky because there are many chances MAC address will change, if the location of the virtual machine changes or If you have a plan to convert a physical server to virtual server using P2V. In that scenarios, Virtual Machine MAC address will change and it will affect the application functionality due to license assignment with old MAC address. MAC address can be bind with the windows operating system using the below method.

1. Log in to your windows server and open up Network connection properties using ncpa.cpl or Open the Device Manager. Click Start > Control Panel > Administrative Tools > Computer Management > Device Manager > Expand Network adapter

2. Right-click on your Virtual Network adapter and select properties.

3. Click on configure and select Advanced Tab

4. Select Locally Administered Address from the Properties.

5. Select the Value and Enter the  value for the MAC Address.

7. click on Ok to bind the MAC address to the Network adapter.

8. Restart the virtual Machine.

9. Ensure that MAC Address Changes & Forged Transmits are set to Accept in your Virtual Switch security policies.

Now we have bind the MAC address to the Virtual Machine Network adapter. It will be always assigned with the MAC Address. We not need to worry about any migrations which may change your MAC Address.
