For example, an inexperienced administrator or a power user might bring up a new DHCP server, unaware that it will cause a conflict on the network. If the service finds itself in the list, it starts processing DHCP requests from clients. Stand-alone servers that are not members of a domain provide a similar capability but through a slightly different mechanism.
If that attempt fails, the client attempts to ping the default gateway defined in its current lease. The client continues to use the existing lease if the ping succeeds, and then checks for a DHCP server every five minutes for a new lease. If the ping fails, the client assumes that DHCP services are not available on the network and automatically assigns itself a non-conflicting IP address in the private address range Click Next to finish the installation.
You use the console to create scopes, which are ranges of IP addresses and their corresponding properties, such as gateway, DNS server addresses, and so on. You also use the console to create superscopes and multicast scopes. Superscopes are an administrative feature that lets you create and manage multiple scopes as a single entity.
Figure D Use the Advanced tab to configure settings for the user class. Disclaimer : Do not attempt to implement any of the settings in this guide without first testing them in a non-operational environment.
Security configuration guides are provided for the Department of Defense and other government agencies requiring security configuration guidelines. The guides contain recommended security settings. They are not intended to replace well-structured policy or sound judgment.
The guides do not address site-specific configuration issues. Care must be taken when implementing the guides to address local operational and policy concerns. All security changes described in the guides are applicable only to specifically identified operating systems or architecture components and should not be applied to any other operating system or architecture components. Product Support : Not provided. These logs may explain why you cannot start the DHCP service.
