DHCP Discover Questions

Hello,

I have an issue where I upgraded device and now clients cannot get an IP address from my domain controller. I've got two of these devices and the other one has not been upgraded so decided to look into both discover packets. There is connectivity between everything and the DC sees the discover packet yet doesn't offer up anything. There's no errors within the server and restarting the services and server didn't help.

  1. Under the DHCP section and Relay agent IP it looks like this. "Relay agent IP address: 10.1.1.0 (10.1.1.0)" this is on the bad pcap vs the good pcap doesn't have the extra IP inside the parenthesis ().

  2. Same scenario for source address under the IPv4 section bad pcap shows "source address: 10.1.1.1 (10.1.1.1) and the good pcap doesn't have the extra IP inside the parenthesis again ()

is the extra IP inside the parenthesis my issue?

Thanks for any help in advance.
