Moving DHCP to another server

Posted on 2013-12-03
Last Modified: 2013-12-03
I need to move our DHCP service from a windows 2003 server to another server but, I will be renaming the new server and changing the IP on the new server to what the current server is named and IP'd. I have already exported and imported the scopes but, what I am not sure of is if I need to authorize the new server into the domain. I was told that since I am keeping the same name and IP address of the old server I won't need to re-authorize the new DHCP service. Is this correct or will I need to de-authorize the original server before I do the renaming and IP'ing of the new server then authorize it.

an add-on question, Should I import the exported dhcp scopes before or after I rename and re-IP the new server?

You need to authorize the new server otherwise you won't get IP address on your clients..

You probably won't need to re-authorize your new DHCP server because your SID will stay unchanged.

Thanks for the reply. I am a little confused by it though. You said I need to authorize the new server but, I won't need to re-authorize DHCP again because the SID stays the same. Do I need to authorize DHCP when I do the renaming or will it stay authorized because the name and IP are staying the same of the new server? What do you mean by the first sentence that I need to authorize the new server?

It will stay authorized because the SID of the computer account doesn't change.

Each windows DHCP server needs to be authorized in AD for DHCP to be functioning currently.

And even if it does de-authorize you can always just re-authorize it.
