part of the domain, they can be used only on subnets where no AD-authorized DHCP servers exist If a stand-alone DHCP server detects an ADauthorized DHCP server on its subnet, it stops its DHCP service This only applies to Microsoft-based DHCP servers A Linux-based DHCP server probably doesn t care what a Microsoft server tells it to do DHCP servers are authorized via the DHCP MMC snap-in s root context menu Select Manage Authorized Servers, as shown in Figure 7-12

DHCP Administration
Let s jump back a step DHCP is managed via the DHCP MMC snap-in that has a shortcut in the Administrative Tools When opened, the local server is loaded in the console Other servers can be added by right-clicking on the DHCP root and selecting Add Server By creating a console with all your DHCP servers, you can quickly get an overview and manage your entire environment from a central location without having to visit each DHCP server separately
Setting Scope Options
Under each server is an IPv4 and IPv6 leaf that corresponds to the two DHCP protocols supported If you created an IPv4/IPv6 scope during installation, it is listed under the IPv4/IPv6 branch You also see a Server Options leaf Although options can be con gured for the scope, some are common for the entire enterprise It makes no sense to keep de ning these

options for each scope you create Instead, they can be set for any scope given from the server under the Server Options For example, items like DNS Servers and Domain Name are most likely common to all scopes from the server and so you ll de ne them under the Server Options Follow these steps: 1 Right-click Server Options and select Con gure Options (see Figure 7-13)
FIGURE 7-13 Notice the options at a scope level Domain Name is already con gured at
the server level
