I have created 3 Win2012 R2 (Evaluations) servers and 3 Win10 Pro (Evaluations) within VMware workstation 5.5. I have made sure that there are in the same NAT network and the connected to the same adapter in Vmware workstation and there can all connected to the internet. I have promoted one of the servers to a domain controller and enabled DHCP, DNS. However when l try to join the VM machines to the domain it says the domain controller cannot be contacted. I have tried to given the VM machines static IP addresses not included in the NAT or DHCP but still l cannot get them to join the domain. I would appreciate any assistance.
