How to Install the DHCP Service
Before you can configure the DHCP service, you must install it on
the server. DHCP is not installed by default during a typical
installation of Windows Standard Server 2003 or Windows Enterprise
Server 2003. You can install DHCP either during the initial
installation of Windows Server 2003 or after the initial
installation is completed.
How to Install the DHCP Service on an Existing Server
- Click Start, point to Control Panel, and then click Add or Remove Programs.
- In the Add or Remove Programs dialog box, click Add/Remove Windows Components.
- In the Windows Components Wizard, click Networking Services in the Components list, and then click Details.
- In the Networking Services dialog box, click to select the Dynamic Host Configuration Protocol (DHCP) check box, and then click OK.
- In the Windows Components Wizard, click Next to start Setup.
Insert the Windows Server 2003 CD-ROM into the computer's CD-ROM or
DVD-ROM drive if you are prompted to do so. Setup copies the DHCP
server and tool files to your computer.
- When Setup is completed, click Finish.
How to Configure the DHCP Service
After you have installed the DHCP service and started it, you must
create a scope, which is a range of valid IP addresses that are
available for lease to the DHCP client computers on the network.
Microsoft recommends that each DHCP server in your environment have
at least one scope that does not overlap with any other DHCP server
scope in your environment. In Windows Server 2003, DHCP servers in
an Active Directory-based domain must be authorized to prevent
rogue
DHCP servers from coming online. Any Windows Server 2003 DHCP
Server that determines itself to be unauthorized will not manage
clients.
How to Create a New Scope
- Click Start, point to Programs, point to Administrative Tools, and then click DHCP.
- In the console tree, right-click the DHCP server on which you want to create the new DHCP scope, and then click New Scope.
- In the New Scope Wizard, click Next, and then type a name and
description for the scope. This can be any name that you want, but
it should be descriptive enough so that you can identify the purpose
of the scope on your network (for example, you can use a name such
as "Administration Building Client Addresses"). Click Next.
- Type the range of addresses that can be leased as part of this
scope (for example, use a range of IP addresses from a starting IP
address of 192.168.100.1 to an ending address of 192.168.100.100).
Because these addresses are given to clients, they must all be valid
addresses for your network and not currently in use. If you want to
use a different subnet mask, type the new subnet mask. Click Next.
- Type any IP addresses that you want to exclude from the range
that you entered. This includes any addresses in the range described in
step 4 that may have already been statically assigned to various
computers in your organization. Typically, domain controllers, Web
servers, DHCP servers, Domain Name System (DNS) servers, and other
servers, have statically assigned IP addresses. Click Next.
- Type the number of days, hours, and minutes before an IP address
lease from this scope expires. This determines how long a client can
hold a leased address without renewing it. Click Next, and then click Yes, I want to configure these options now to extend the wizard to include settings for the most common DHCP options. Click Next.
- Type the IP address for the default gateway that should be used by clients that obtain an IP address from this scope. Click Add to add the default gateway address in the list, and then click Next.
- If you are using DNS servers on your network, type your organization's domain name in the Parent domain box. Type the name of your DNS server, and then click Resolve to make sure that your DHCP server can contact the DNS server and determine its address. Click Add to include that server in the list of DNS servers that are assigned to the DHCP clients. Click Next,
and then follow the same steps if you are using a Windows Internet
Naming Service (WINS) server, by adding its name and IP address. Click
Next.
- Click Yes, I want to activate this scope now to activate the scope and allow clients to obtain leases from it, and then click Next.
- Click Finish.
- In the console tree, click the server name, and then click Authorize on the Action menu.
