DHCP Server address conflict parameter with Windows Server

Using the DHCP Server component within Windows Server, an option is present to attempt to detect IP address conflicts.  To access this option, right-click the IPv4 node in the DHCP management console and click on the Properties selection.

Access the Advanced tab.  The default value is 0; enter 1 to have the service attempt to verify the address value it is about to assign is not currently in use.
