Use IP conflict detection only when it is needed

When two devices on the same LAN have the same IP address an IP address conflict occurs. This leads to one or both of the devices having issues communicating on the network.

The DHCP server has an option to help reduce IP conflicts. The conflict detection option on the DHCP server will first check if an IP is in use before assigning it to a device.

By default, this is disabled on all DHCP scopes.

Microsoft’s recommendation is to use this only when it is needed. DO NOT enable this for every scope. If you stay away from static IP assignments then you probably will never need to turn this on.

If you do turn this on set the detection attempts to 1 or 2.
