The way you have it currently set, you have two different settings but both are beyond the lease time. Therefore, the client machine will asking for a refresh every four hours. This value does not change after upgrading all domain controllers to newer Windows versions or by changing the Domain or Forest Functional Levels. So you would think a shorter lease time would work.
