Instructions on how to Install and Configure DHCP on the Curriculum and Admin Windows 2003 Server

How to Install DHCP

The main task of the DHCP server is to give IP addresses and other configuration parameters as a computer joins the network. To begin installing DHCP services on the Curriculum Server for Windows 2003, open your control Panel: Start>>Settings>>Control Panel and then click on ‘Add or Remove Programs’ The below screen will now appear. Double click Add/Remove Programs

Scroll down and select ‘Networking Services’ and then click on ‘Details’

After selecting ‘Details’, the following screen will emerge. Tick the box named ‘Dynamic Host Configuration Protocol’ and click Ok. Click ‘Next’ to continue…..The initial installation of DHCP will now begin (Please insert the appropriate disc i.e. 2003, if you are prompted for one)

Click ‘Finish’ and close any other windows that may be open

How to Configure DHCP

Please note that the only difference between the Admin and Curriculum configurations is specifying the IP ranges for each network. To configure DHCP please navigate to the following: Start>>Programs>>Administrative Tools>>DHCP

The following screen should now appear: A new ‘New Scope’ has to be created, this is achieved by Right clicking on the Domain name (In the example below the Fully Qualified Domain Name is lln-a.2ksvr.lln-a.local) and select ‘New Scope’

Click ‘Next’ to continue… The information entered within the empty fields below does not affect the configuration of DHCP, however we recommend that you enter YOUR schools name within the ‘Name’ field and enter Scope Wizard for the ‘Description’

The next screen represents the range of IP addresses that will be given out by DHCP server when using the scope specified in the previous screen. Please ensure that you type the following for the Subnet Mask

• For Admin Networks please enter 255.255.255.0 as the subnet mask • For Curriculum Networks please enter 255.255.252.0 as the subnet mask • For Curriculum Networks do not use the top 32 and the bottom 32 IP

addresses IE: 10.5.252.33 to 10.5.254.223 (Please note the ‘Start’ and ‘End’ IP addresses will be different for the Admin server) Within the next screen you will be asked for a list of IP addresses that should be Excluded from the range you have specified within the last screen. If there are any devices on the network that have been assigned IP address within the range specified on the previous screen they need to be added below, as DHCP may issue these IP address as a new clients join the network.

Here we need to specify the pool of IP addresses that the DCHP server will assign to clients on the network. Within this screen we have specified a range of 500 IP addresses

The below screen represents the allocated amount of time that the client leases an IP address from the DHCP server. (This is defaulted to 3 Days) LLN recommend that this is kept to 5 days.

Within the below screen select “Yes, I want to configure these options now” and click ‘Next’ Enter your Default Gateway IP address (The last octet will always end in .254 regardless of which server DHCP is being installed on) Click Add and then click Next to continue….

The next screen specifies the IP address of the DNS server. If you are running Windows 2000 or 2003 please ensure that the IP address of the ‘Local DNS Server’ is inserted first within the list. You also need to specify the DNS servers at Leeds Learning Network (See below). (Please note the local DNS will be different for the Admin server)

The following screen is only to be configured if the school has a WINS Server. If so, please enter the IP address of the server and click ‘Next’

Leeds Learning Network’s DNS Server

Local DNS Server

The screen below corresponds to activating the scope for the DHCP server and IP address will now be issued to any new comers to the network. Select ‘Yes, I want to activate this scope now’ and click ‘Next’ to continue.. Click ‘Finish’

After the DHCP has been configured, you may be asked to ‘Authorise the DCHP Server’ (see below) To authorise the server, Right click the domain name (In this case the domain name is lln-a.2ksvr.lln-a.local)

Click ‘Authorise’ and close down any windows open. DHCP has now been successfully installed and configured.
