This section describes how to develop strategies for placing DHCP servers on small-scale and large-scale installations. Most network administrators implementing DHCP will also be planning a strategy for implementing WINS servers. The planning tasks described here also apply for WINS servers. In fact, the administrator will probably want to plan DHCP and WINS implementation in tandem. The following procedure describes the general planning tasks for planning DHCP and WINS implementation.
For example, the plan could define units of the organization to be phased into using DHCP and the order for types of computers to be phased in (including Windows NT servers and workstations, Microsoft RAS servers and clients, Windows for Workgroups computers, and MS-DOS clients).
Be sure that the pilot project addresses all the requirements identified in step 1.
This task can include determining strategies for backup servers and for partitioning the address pool at each server to be provided to local versus remote clients.
While planning, remember that the actual placement of the servers in the physical network need not be a major planning issue. DHCP servers (and WINS servers) do not participate in the Windows NT Server domain model; domain membership is not, therefore, an issue in planning for server placement. Because most routers can forward DHCP configuration requests, DHCP servers are not required on every subnet in the internetwork. Also, because these servers can be administered remotely from any Windows NT Server computer that is DHCP- or WINS-enabled, location is not a major issue in planning for server placement.
