???:In the console tree, select the DHCP server on which you want to create the new DHCP scope.
Right-click the server, and then clickNew Scope. In the New Scope Wizard, clicknext, and then type a name and description for the scope. This can be any name that you choose, but it should be descriptive enough to identify the purpose of the scope on your network. For example, you might use Administration Building Client Addresses.
Type the range of addresses that can be leased as part of this scope, for example, 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 should 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.

Type any IP addresses that you want to exclude from the range you entered. This includes any addresses that may have already been statically assigned to various computers in your organization. ????? ????,next.

Clients are unable to obtain an IP address If a DHCP client does not have a configured IP address, it generally means that the client has not been able to contact a DHCP server. This is either because of a network problem or because the DHCP server is unavailable. If the DHCP server has started and other clients have been able to obtain a valid address, verify that the client has a valid network connection and that all related client hardware devices (including cables and network adapters) are working properly.
The DHCP server is unavailable When a DHCP server does not provide leased addresses to clients, it is often because the DHCP service has failed to start. If this is the case, the server may not have been authorized to operate on the network. If you were previously able to start the DHCP service, but it has since stopped, use Event Viewer to check the system log for any entries that may explain the cause.
