Manually changing MAC addresses
Serdar Yegulalp
The MAC address (or Media Access Control) of a network adapter is a hardware-level ID number that uniquely identifies a network card. Some network cards come with a MAC address hard-wired, but some can have their MAC address changed through software. (Check the network card's documentation to see if this is possible.)
If your NIC is one of the latter, then you can use the following procedure to edit the MAC address in Windows 2000.
The maximum value for a manually generated MAC address is shown in the sample. Ethernet.address = 00:50:56:3F:FF:FF. You must also set the address type in a virtual machine’s configuration file. Ethernet.addressType='static' Because ESXi virtual machines do not support arbitrary MAC addresses, you must use the example format. Feb 01, 2002 Manually changing MAC addresses Serdar Yegulalp.

The same change can be made directly to the Registry:
Either way, when you make the listed changes, you need to reboot the computer. After rebooting, open up a command prompt and type ipconfig /all to verify that the new address has taken effect.

I think we are all familiar with the manual MAC address issue - some software depends on the MAC for licensing, and in VMware you need to stick to a certain range of Ethernet addresses if you want to be able to manually put in your own MAC address.
Somehow I think that should have been written in big, bold letters before I started virtualizing a couple of years ago. I'm pretty sure it wasn't mentioned in the class, either. I have several apps that generate their license based on a server's MAC. And yes, now I have to change virtual NICs on several VMs from either Flexible or E1000 to VMXNET2.
Currently running vSphere 4.1, ESX build 320092 across the board.
Since I didn't plan ahead far enough to manually put in those MAC addresses, now I have no choice but to find some way to keep them until the vendors can regen the licensences.
So, here's the procedure I'm using to keep the MAC address:
1) Write down the old MAC
2) Replace Flexible NIC with VMXNET2
3) Unregister the VM
4) Edit the .vmx file and replace the automatically assigned MAC address with the old MAC address Mcculloch 10 10 bar.

5) Re-register the VM with the host

So far it has worked for me just fine on two test servers. The question is: Will this cause any problems down the road?

I am currently running a 'vanilla' network setup - no distributed vSwitches. However I do plan on putting that in place later this year, and that's where I'm not sure it my little procedure will come up to surprise me at that point.
