How we fix DHCP failover error 20010

Now let’s take a look at the solution our Support Engineers provide to resolve this error.

1. Ensure that all the custom settings from the primary DHCP server are also mirrored on the other server. Because it is possible that those customizations are vast and numerous. The rule is if you have more customizations to replicate then you are prone to more human errors.

Right-click on IPv4 and select “Set Predefined Options”, here you can confirm if both the DHCP servers had the same custom options created.

2. It is always good to have a backup of the DHCP settings when no one needs it. You can take the backup by clicking on the server name under the DHCP console and select backup. After that, copy the folder that you backed up to the secondary server. Then restore from that backup. Finally, delete all scopes on the secondary server.
