    I have 2 macs in the office on the same network. The second machine is using a copy of the Virtual Machine made on the first. I have changed the ethernet hardware address for both of them in the network advanced tab.

    Unfortunately, the DHCP server insists on giving them the same IP address, even through they now have different ethernet mac address (which I can verify by doing an ipconfig /all).

    Any ideas how to fix this besides giving them static IP addresses (which would make travelling off network a pain) ?

    Thanks,
    Ken

    You might try changing the machine name in one of them. Some DHCP servers use that to identify a machine (for some strange reason -- who would think of using a name to identify someting?).

    If this is a network you control, you might try looking at the logs on the DHCP server to figure out why it is giving you the same IP address for both machines?

    Windows based DHCP servers use strange things to identify machines. Back when I was cloning Win2K (for high school writing labs) I remember we had to run a little utility on each one to change something in the registry to make sure that the DHCP server didn't assign the same address to all of them. I don't remember what had to be changed though... that was years ago...

    Maybe the installation ID in the registry?
