  • Help moving DHCP and DNS from one server to another

    Hello,
    I am retiring one of my servers that is currently running DHCP and DNS for my organization. How would I move DHCP and DNS from one server to another.
    Same domain, different OS (not sure if it even makes a difference) Old server Win 2000 new server is server 2030.
    Thanks

    Windows 2030 -- that would be the early Beta version then?
    Moved to Server 2003 forum for more response

    For DHCP, set it up on the new server, create the same scope as the old and then:
    1) Change old scope to very short (1h) leases
    2) Wait 50% of old lease duration so all have picked up new leases (or get users to repair LAN connection to get new leases
    3) Authorise new server & Activate scope
    4) Deactivate old scope

    There are probably ways involving transferring the DHCP database

    DNS will depend on whether it is AD integrated or not -- more info please

      More easy for dhcp; Use netsh to dump your current DHCP config and import it in the new one.
      Oh I just found a MS article about it (scroll down a bit)

      Shorten the lease time isn't required although recommended. The client will search automatically for a new DHCP server when the old one doesn't respond.
