Netware 6.5 and DHCP
I need to move 2 scopes off of 1 Netware 6.5 SP5 server and move each to remote sites on their own DHCP servers, which are also Netware 6.5 SP5. I need some detailed information on this process. Can I disable the existing scopes and use them later for backup purposes if the other servers go down as well?
Yes, you can "disable" the existing DHCP scopes (instructing the current DHCP server to not service them), and create new scopes for the remote sites, instructing the DHCP server instances at those sites to serve those specific scopes.
If your routing configuration does not forward DHCP requests (which are generally limited to the local network), then having the original server able to pick up the other scopes in the event of a remote site server failure is not of much use. There is also the problem that the original server will not have a current lease database, and might make the mistake of leasing an address already in use.
Since NetWare v6.5 *includes* a 2-node license for Novell Cluster Services (NCS) v1.7, if DHCP is such a critical service at these remote sites, then why not simply implement a clustered solution at each site? There's no licensing charges (Netware v6.5 and eDirectory are licensed per-user-seat; the number of servers is irrelevant), just what it takes in hardware.
Alternatively, if appropriate to your environment, just set a long lease time (the default is 3 days).

Same tree?

Yes, the servers are in the same tree. They do not host DNS services. DHCP packets are forwarded. Can this still be done without using the DNS services portion? There is a MS server hosting the DNS zones. You make some valid points and it sounds like the cluster services are the way to go on this scenario. I can do this for free with the 3 servers? Can I maintain the DHCP configuration of the original DHCP server without re-configuring the scopes?
