The Conflict detection attempts parameter on a Windows DHCP server instructs the server to attempt to ping the IP address it is about to assign to determine if the IP address is already in use.
This helps to prevent duplicate IP addresses on the network. In Windows, this parameter takes the number of pings as its value.
To set conflict detection:
- Select the server for which you want to add the conflict detection option.
- Select the Deployment Options tab.
- Under Deployment Options, click New, then select DHCP Service Option.
- From the Options drop-down menu, select Conflict Detection.
- Select the Enabled check box.
- Under Change Control, add comments, if required.
