DHCP

By clifton ·
Good day forum. I have two 2012 R2 servers hosting our DHCP environment. One primary site and another DR(secondary site). These are in a failover state for the scopes. Over time perhaps some things got out of sync from primary to secondary probably due to human error. But now I have one scope on the the secondary that does not exist on the primary. I've asked around and some people say export the dhcp scopes from the primary and import on the secondary. These people say this will not overwrite anything but I'm not so sure about that. I can't delete the scope as it is in use and it will not allow me to try and sync with the error 87.

At least it's in extended support.

It's not unusual for the IT lead to reboot this and take it offline (we unplug the Ethernet) to do such updates.

-> You do have a lot of work ahead to keep this secure. Example:
