    Where does VMware get it's MAC address from.

    VMware has been installed by another company where I work on a number of machines


    They install VMware, then copy from a working VMware machine call it machine 1, all the VMware files from "Vmware " folder on working machine. (machine 1) to the newly set up vm pc's.

    In copying from one machine to another, does this mean the mac address will be copied from machine 1 to the newly set up vm pc's.

    (PS I think they may have copied one set of VM files, and some time later, copied another set of vm files from another machines, lets call it machine 2)

    Reason I ask I captured the mac address last week and now macs have changed

    When a virtual machine is powered on, the VMware application automatically assigns it a MAC address. The software guarantees that virtual machines are assigned unique MAC addresses within a given host system. However, the software does not guarantee that a given virtual machine is assigned the same MAC address every time it is powered on.
    If you want to guarantee that the same MAC address is assigned to a given virtual machine every time, even if the virtual machine is moved, or if you want to guarantee a unique MAC address for each virtual machine within a networked environment, you can assign the address manually instead of allowing VMware Workstation to assign it automatically.
