What is ctDhcpDeclines?
ctDhcpDeclines is a read-only counter of the number of DHCPDECLINE messages received by the DHCP server since its last reset, which clients send when they detect the offered address is already in use. An admin watches this counter because a rising value indicates address conflicts on the network, often caused by statically configured devices squatting on addresses from the DHCP pool. For example, a steady trickle of ctDhcpDeclines would prompt an admin to check for a statically-addressed device conflicting with the DHCP scope's address range.
