You must create a DHCP scope for each subnet in your network. Each subnet has a DHCP scope, with a single continuous range of IP addresses.

Before you create scopes, you must install DHCP on your server. For more information about installing DHCP, see "Checklist: Installing a DHCP server" in Help and Support Center for Windows Server 2003.

You can use the DHCP MMC snap-in to create a new scope on your DHCP server.

To create a DHCP scope

  1. In the DHCP snap-in, select the name of the DHCP server.

  2. Select Action, andthen select New Scope. This opens the New Scope Wizard. Complete the New Scope Wizardby configuring the following properties:

    • A scope name and description of the scope.

    • A consecutive range of possible IP addresses.

    • A unique subnet mask. For more information about defining subnet masks, see “Designing a TCP/IP Network" in this book.

    • The IP addresses that are to be excluded from the scope.

    • Lease duration values.

    • Options.

For a worksheet to assist you in completing the New Scope Wizard, see the "Scope Data Collection Worksheet" (DNSDHC_1.doc) on the Windows Server 2003 Deployment Kit companion CD (or see the "Scope Data Collection Worksheet" on the Web at https://www.microsoft.com/reskit).

After you create the scope, you can set reservations and configure any additional DHCP options. For information about setting reservations, see "Creating Reservations" later in this chapter. For information about configuring additional DHCP options, see "Configuring DHCP Options" later in this chapter.
