I have a Windows 2003 Server guest that I migrated from a VMware Server to an ESX Server. In the migration the MAC address was changed. This is a real problem since this is a licensing server and the license keys are based on the MAC address. I'd like to manually set the address back to what it originally was when the guest was on my VMware Server host. I've seen where I can go into the settings and manully define a MAC address via the GUI but it will not allow me to change the first 3 octets from the ESX default.
Can I, and if so, how do I change the MAC address? Can I just log into the console on the ESX server and edit the settings manually? I know I could just request new keys based on the new MAC address but this is not a trivial process. Just fixing the MAC would be much faster. Thanks.
