You should configure a DHCP superscope.
Explanation:
The problem here is that after the host #200 is connected to your LAN, the next host IP is going to be the APIPA Address(Automatic Private Internet Protocol Addressing) because the server don´t have any IP to offer, in windows server you must configure a feature of the DHCP service called superscope. A superscope is a feature of Windows Server DHCP that enables to serve multiple IP subnets to the same physical LAN, this feature will enable another subnet in your system so any host connected must have a valid IP address.
