  • Domain Name Change of DHCP Server

    Whats steps (other than changing the domain name) do I need to take to ensure continued functionality of a DHCP server when I need to change it from one domain to a new domain (in a different forest). Do I just need to make sure its "authorised" in the new domain once it appears? Will there be a period where the DHCP server cannot hand out addresses while this "Authorisation" replicates/processes?

    Cant find too much info on the affects of a domain name change on a DHCP server on google. The IP address and server name will remain the same.

    Thanks

    Forgot to say, old domain is 2003 and new domain is 2008. DHCP server is 2003.

      Should just be a case of
      In old domain:
      Unauthorise
      Disjoin server from domain

      In new domain:
      Join server to domain
      Authorise

      Authorisation is immediate as it is only the DHCP server which gets authorised...

        OK, thanks for that. Doesn't sound too bad then.

          OK, as a continuation on the theme, is it necessary to unauthorize the old DHCP server before authorizing a new one? I've recently tried moving the DHCP scopes from a 2003 server to a 2008 one. I exported the database from the current server, imported it to the new server, turned off the old server, made sure the new server was authorized, but I have no DHCP action on my network with that setup. Would this be a cause?

            If your DHCP is on a different VLAN make sure the switches / routes are updated with the new IP helper address

              Bleh, I knew there would be a catch. Been a few years since I've dealt with IP helper statements. Thanks!
