I have ZCM11 setup on a windows 2008r2 server which is hosted on a VMware esxi5.1 station.
Proxy DHCP is working just fine and the client comes down with no problems. It is when I try to send a image up I get the error
"network is unreachable. Unable to connect to the server."
I can ping the server from the workstation,
I have turned the firewall off, and still no different results.

I have a different network that the imaging works just fine on.
