This section describes how to configure DHCP services on a Windows
2003 Server.
Some of the DHCP options in the examples in this section are configured
as system-wide options while others are configured at the scope or
reservation level. If necessary, modify the examples to conform to the
norms used in your network design. For example, if you use more than
one Network Time Protocol server per regional office, you may want to
configure DHCP option 42 (NTP Server IP Address) at the scope level (for
each branch office) rather than at the server-wide level (for all branch
offices).
Preparation Steps To automate the branch office server installation you must first perform
these preparation steps:
■
On a DHCP server that will service requests from the branch offices,
create,
but do not configure the options listed in Table 19 as
server-wide options. These options are then available for configuration
within all scopes and will be configured within each individual scope.
See
“Options 60, 120 and 184” later in this appendix.
■
On the DHCP server, configure the options listed in Table 20 as
server-wide options. These options are then preconfigured for all
branch office scopes. See
“Options 6 and 42” later in this appendix.
■
On the DHCP server, create one DHCP scope per branch office. For
each scope, configure the options listed in
Table 21 . See “Configuring
DHCP Options for Each Scope” later in this appendix.
