Enable IP Address Conflict Detection on Server 2012

Enable IP Address Conflict Detection in DHCP on Server 2012

I have many times had to turn on the address conflict detection on a server with the DHCP Role installed  Although Windows 2003 server also had this feature /role and the steps to enable ip address conflict detection differs slightly on Windows 2008 and 2012 Server. The procedure is very similar or the same. The following procedure can be used to specify how many times the DHCP server sends a ping out and tests an IP address is available before leasing it to a client.

The requirements to complete the procedure is Membership in the Administrators or DHCP Administrators group. That is the minimum requirement.

Enable address conflict detection

1. Open DHCP Management Console.

2. In the DHCP Management Console tree, click the appropriate DHCP server.

3. From the Action menu of the console, click Properties.

4. Click on the Advanced tab of the Properties window.

5. Type a number greater than 0 (zero) and less than 6 for Conflict detection attempts to be performed. The number you type determines how many times the DHCP server will tests an IP address before it is leased to a client. Once the value is set, click OK.
