The Windows Server operating system contains the DHCP Server components.
This section describes how to set up and configure a new Windows DHCP server in a Windows Active Directory domain. The Windows DHCP service provides clients with IP addresses and information on the location of the particular standard gatekeeper, the DNS server, and the WINS server.
Note: We recommend that you use a DHCP server in the DLS environment to support full Plug&Play and ensure the authenticity of the DLS server.
Installation
You can install DHCP either during or after the original installation of Windows Server or Advanced Server. However, there must be a functioning DNS server configured in the environment. This allows active DNS forwarding via DHCP.
To check the DNS server, click Start, then click Run, enter cmd, press the <ENTER> key, enter ping [name displayed for the DNS server in your environment] and then press the <ENTER> key. If the query is unsuccessful, the message "Unknown host [DNS server name]" will be displayed.
To install the DHCP service on an existing Windows Server, proceed as follows:
1. In the Windows Start menu, select Start > Settings > Control Panel.
2. Double-click Add/Remove Programs and then select the option 'Add/Remove Windows Components.
3. In the Windows Component Wizard, click Networking Services under Components and then click Details.
4. Activate the DHCP (Dynamic Host Configuration Protocol) check box if it is not already activated, and then click OK.
5. In the Windows Component Wizard, click Next to start the Windows setup program.
6. Insert the Windows Advanced Server CD-ROM into the CD-ROM drive when you are prompted to do so. The setup program copies the data for the DHCP server and the DHCP tool on to your computer.
7. When setup is complete, click Finish.
General Configuration
After you install and start the DHCP service, you must create a scope (a range of valid IP addresses that are available for leasing to DHCP clients). Each DHCP server in your environment should have at least one scope which does not overlap with another DHCP server scope in your environment.
Normally, the server is authorized when the server is first added to the DHCP console during installation and configuration of the DHCP service. If you install and configure the DHCP service on a member server or standalone server, however, you must configure the DHCP server.
To authorize a DHCP server, proceed as follows:
1. In the Windows Start menu, select Start > Programs > Administrative Tools > DHCP.
You must be logged on to the server with an account that is a member of the "Organization administrators" group.
2. In the DHCP console menu, select the new DHCP server. If there is a red arrow in the lower right corner of the server object, the server has not been authorized yet.
3. Right-click the server, and then click Authorize.
4. After a few moments, right-click the server again, and then click Refresh. The server should now be shown with a green arrow in the lower right corner, which indicates that the server has been authorized.
To create a new scope, proceed as follows:
1. In the Windows Start menu, select Start > Programs > Administrative Tools > DHCP.
In the console structure, select the DHCP server on which you want to create a new DHCP scope.
2. Right-click the server and then left-click New Scope.
3. In the scope creation wizard, click Next and then enter a name and description for the scope. You can choose any name but it should provide a good description of the purpose of the new scope in the network. For example, you could enter "Client addresses in the administration building".
4. Enter the address range that can be used as a lease in this scope, for example, from the starting IP address 192.168.100.1 to the end address 192.168.100.100. Because these addresses will be issued to clients, they should all be valid addresses in the network that are not currently in use. If you want to use another subnet mask, enter the new subnet mask. Click Next.
5. Enter all IP addresses that should be eliminated from the scope that you entered. This includes all addresses that may have already been statically assigned to different computers in your organization. Click Next.
6. Enter the number of days, hours, and minutes after which an IP address lease from this scope expires. This specifies the time period for which a client can hold a leased address without having to renew it. Click Next.
7. Select Yes, I want to configure these options now and then extend the wizard to add settings for the most common DHCP options. Click Next.
8. Enter the IP address of the standard gatekeeper that should be used by clients that have received an IP address from this scope.
9. Click Addto include the standard gatekeeper address in the list, and then click Next.
10. Click Yes, I want to activate this scope now to activate the scope and allow clients to take leases from the scope.
11. Click Next and Finish.
