Cannot get VMs to talk to Domain Controller

I have setup SCVMM 1801 on a standalone machine that I cannot get any of the VMs on board to talk with the Domain Controller that hosts the SCVMM console. Sometimes I can ping, sometimes I cannot but every time I run ipconfig I get a 169.254 IP address. I know that means it cannot talk to the DHCP server I setup but I have configured two virtual switches (internal and external) but 0 luck. I am not sure what I am missing here, any pointers? I also have two physical laptops that are hardwired into this network that have no issue connecting to the DC and DHCP server.
