Based on that message, I would suspect that probably either: - the DHCP server is not seeing distinct MAC addresses from your VMs vs your host, or - you have actually exhausted your DHCP address pool. I'd look at those two first, based on what you see in your dhcp server log. You may have to get your dhcp server to tell you what leases are currently in use. Devin
