We currently have two DNS servers at our HQ and 1 DHCP. I would like to have another DHCP server added for dedundency and replication. Is there a way that this information can be imported onto the new server?

    Just do a dhcp backup from one server to the other
    If you want redundancy have one server distribute for example 10.0.103.??? To 10.0.105.???
    And have the other do 10.0.106.??? To 10.0.109??!

    Accepted Solution

    There is no possibility to synchronize 2 DHCP servers. There is no mechanism. You have to split scope(s) by yourself or prepare additional DHCP server which is not running. Copy from the first one from %WINDIR%\SYSTEM32\DHCP database and stop DHCP Server service on the second one. Then copy database there, and in case of failure the first one, enable DHCP Server service on the second one.

    Important! Remember that you have to do DHCP database copy regurarly to have the latest leases within it!

    If you have 2008 R2 DHCP servers then you can use Split-Scope feature. For more info lease visit my blog at
