We have a Primary DHCP Server (2012 R2 Standard). We are trying to Configure a DHCP Failover with Server 2016. There are 3 Scopes. Two Scopes, we successfully managed to do the Failover. There is one Scope which is failing on the Failover (Configure Failover failed: Error: 20010. The specified option does not exist). I have checked "Set Predefined Options" and it does match on both Servers. Could somebody please assist here?

    Hi ,

    Please check whether you have one or more custom DHCP attributes. As picture below:

    Please make sure you have created the same custom attributes on your partner server:

    Then we should configure failover successful:

    I have checked "Set Predefined Options" and it does match on both Servers.

    Please post some screenshots to help us confirm the configuration.

    Best Regards,
