Configure failover failed. Error: 20114: The DHCP Failover relationship already exists.

This post relates to the new Windows Server 2012 Failover technology.  I was diagnosing DHCP Issues at a customer when I was required to remove my DHCP scopes from failover configuration then re-add them.  After attempting to re-add the scopes I received the following error.

Configure failover failed.  Error: 20114: The DHCP Failover relationship already exists.


Despite removing the scopes from DHCP failover the partner server still believes the DHCP failover relationship was in existence.

After messing around a little longer I found out a work around.  The error was occurring because I was using the same Relationship Name as before.  Changing the Relationship Name to something else resolves the issue.
