i have two VLANS (84VLAN and 86VLAN). Our DHCP server has two NICs configured to provide DHCP service from two Scopes to the two vlans. however, i have recently noticed some section of the 86VLAN are not able to get IP address from the server (IP Address conflict messages). I have enough IP addresses for the VLAN for each vlan. I suspect the server is not handling DHCP requests well hence the issues. where do i look?
