DHCP and Remote Access Overview
When a remote computer connects to a remote access server (RRAS), it is automatically provided with an IP address when the Point-to-Point Protocol (PPP) connection is established.
You can configure the RRAS server to allocate IP addresses to remote clients from:
A static range of IP addresses: This method is usually implemented when there are no internal DHCP servers.
An existing DHCP Server: This is achieved by relaying clients to the DHCP server for IP

The DHCP server role is responsible for dynamically assigning IP addresses to DHCP clients, and for assigning additional TCP/IP configuration information to DHCP clients as well. This includes subnet mask information, default gateway IP addresses, Domain Name System (DNS) server IP addresses, and Windows Internet Naming Service (WINS) server IP addresses.
A DHCP must have at least one scope which consists of the IP addresses which the DHCP server can allocate or assign to DHCP clients. Scope

Users can use the Event Viewer tool in the Administrative Tools folder to monitor DHCP activity. Event Viewer stores events that are logged into the system log, application log, and security log. The system log contains events that are associated with the operating system. The application log stores events that pertain to applications running on the computer. Events that are associated with auditing activities are logged into the security log. All events that are DHCP-specific are logged into th

The Dynamic Host Configuration Protocol (DHCP) is a service that runs at the application layer of the TCP/IP protocol stack to dynamically assign IP addresses to DHCP clients, and to allocate TCP/IP configuration information to DHCP clients. This includes subnet mask information, default gateway IP addresses, DNS IP addresses, and WINS IP addresses. The DHCP protocol is derived from the Bootstrap Protocol (BOOTP) protocol. The DHCP server is configured with a predetermined pool of IP addresses (

An Overview of DHCP
In TCP/IP based networks, a unique IP address must be assigned to each computer. An IP address is a unique numeric identifier that identifies computers on the network. The Dynamic Host Configuration Protocol (DHCP) is a service that can be implemented to automatically assign unique IP addresses to DHCP clients.
DHCP runs at the application layer of the TCP/IP protocol stack to provide the following functions in TCP/IP networks:
Dynamically assign IP addresses to DHCP

Management Tasks for the DHCP Server
The common management tasks that you need to perform for your DHCP servers are listed below:
Delegate DHCPadministration to individuals.
View and analyze DHCPstatistical information.
Change the status of the DHCP service.
Configure superscopeadministration entities.
Back up the DHCPserver database.
Restore the DHCPserver database.
Repair a corruptedDHCP server database.
Move a DHCP databaseto a different DHCP server.

Configuring the DHCP Server Environment
The primary steps required for configuring and managing your DHCP server environment are:
Install the DHCP service on a server.
Authorize the DHCP server in Active Directory.
Configure the necessary DHCP scopes for your subnets.
Configure superscopes and multicast scopes.
Configure the DHCP lease duration.
Configure the DHCP options.
Configure the DHCP reservations.
Configure the BOOTP tables.
Configure DHCP and DDNS integration.
