Here is another capture. This machine was connected to LAN, no WiFi or any other connectivity: https://www.dropbox.com/s/iuvzqo1vxm9...
This PC was on the 6th floor on vlan 1401. The phone on the desk is in vlan 1361. Default gateway for vlan 1401 is 10.36.140.2 & 3 /22 (2 core switches) and default gateway for vlan 1361 is 10.36.136.2 & 3 /22
In the DHCP responses, the gateways address that is provided is 10.36.136.1 and 10.36.140.1 instead of the .2/.3 addresses you are referring to. Then looking at the ARP traffic, there are no repsonses to the ARPs for 10.36.136.1/10.36.140.1, so I guess you do only have the gateways at the .2/.3 addresses.
This either means the DHCP server has been configured incorrectly. But I assume you want to use a First-Hop-Redundancy-Protocol like HSRP or VRRP and that the gateway indeed should be the .1 address pointing at the HSRP/VRRP address. Going back to your trace and filtering on "vrrp || hsrp" is indeed showing VRRP packets advertising the .1 addresses. So the DHCP server is configured correctly and the gateways are indeed configured with the virtual addresses 10.36.136.1 and 10.136.140.1.
Then the problem is concentrated on why the (active) gateway is not responding to ARP requests for it's VRRP addresses. Could this be a configuration issue on the gateways?
Interestingly, on this capture, I'm seeing dhcp/bootp errors. How do I resolve these?
What kind of DHCP errors do you see?
