Hi,

we had our partner IT Company create DHCP Failover, but they entered a wrong shared secret password. How can I change this?

Cheers!

    Hi Leon,

    thank you. This is correct, however I get the message that "The DHCP Server service is not running on target computer". I have checked the services on both DCs/DHCPs and they are running?

    Cheers

    Hi,

    I had to delete the failover configuration and set it up again. This was the only way. The MTU were correct. Anyways it is working now.ž

    Thank you for your help.

    Cheers!
