I am stumped at the moment. I have been through 2 different DHCP servers, server 2008 and now server 2016. I moved to server 2016 because of the same issue. I have manually configured the scopes and we have a flat network of Cisco 3800's, some connected via fiber, which can do L3 but we are doing L2 and no routing. approximately 325 devices on the network.
The DHCP server is handing out anything in 172.16.20.x but not 172.16.21.x even though it is part of the scope. Users are calling me saying their pc is not getting a network connection and when I am seeing that they are not getting a DHCP address unless I create a reservation in any range (inc. 172.16.21.x) or delete a lease in the 172.16.20.x range. I am going to connect a PC to the same switch as the DHCP VM and see if it can get an address and then I will go to other areas. I also have wire shark. No errors in the DHCP or server logs. I know I need a relay agent if there are different subnets but this is one subnet with a 255.255.254.0 /23 mask.
I would appreciate any ideas or suggestions. thanks
