Windows 2000 Configure DHCP Server

After installing the DHCP-server, you will need to configure it before you can use it:

Select "DHCP" , which is part of the
Windows menu "Administrative Tools".

In the left plane, you will see the name
and IP-address of the DHCP-server.

After installation, a DHCP
server is not authorized.
Do not forget this later !
( see below )

You need to define the range of IP-addresses to be assigned (=distributed) by the DHCP-server.
A definition of a range of IP-addresses (with or without additional options) is called a "Scope":
select your DHCP-server and then either with a right-click or from the menu "Actions" select to
define a "New Scope":

	Up comes the Wizard select "Next"
	Define a name for your scope continue with "Next"
	Define the range of IP-address and the subnet-mask. Select a range, which does not include the IP-address of the server itself or any other device with a manually assigned IP-address (like: network printers). Although you could exclude them in the next step, usually a range is reserved for such manually assigned addresses and then the rest (in this case: 100 - 199 ) is given to the DHCP-server for automatic distribution.
	If you could not define separate ranges for manually assigned and DHCP-assigned IP-addresses, then you could here define IP-addresses or ranges of IP-addresses to be excluded: not to be used by the DHCP-server.
	Typically, an IP-address is assigned (= "leased" ) for a limited time. This avoid running out of addresses, when visitors to you office connect to the network and get an IP-address assigned. Without a time-limit, such an IP-address could not be reused. usually, 8 days is a good choice and will ensure that people every day in the office will \|continue to use the same IP-address once assigned to them, since their systems will in time extend the "lease". And if they come back from a 2 week vacation and the "lease" has expired, then the DHCP-server will assign a new IP-address to them.
	In addition to the IP-address and Sub-Netmask, a DHCP- server can also be use to define other TCP/IP configuration items on the Client systems.
	Is your office network part of a larger company Wide-Area network (WAN ) ? Then you need to configure the client computers with the IP-address of the Gateway (or Router) to be able to communicate with systems on the WAN. Enter the IP-address and then click on "Add" to enter the address to the list of Gateways.
	Are you using a WAN and need to help your clients to locate the IP-addresses of servers (like WebServers) on the WAN ? Or do you intend to have clients connected to the Windows2000 server via the new :"Active Directory" method ? Then you must configure the clients for use of a DNS-server. Enter the name of your server and the IP-address and click on "Add" to enter the value on the list.
	You can also configure the WINS server address
	You need to activate the scope, ( which you can do later with a right-click on the scope and selecting : "Activate"/"Deactivate" :)
	Finished.

You still have to "Authorize" the DHCP-server:
select the server and either right-click or from the menu "Action" select "Authorize" :

Note: on my system, I had to close now the DHCP-windows and open it up again to see,
that the DHCP-server is now "Running" :

a quick check on the "Scope Options", which we have configured already:

If required, you can change or add
the options of the scope.

You can configure in the "Properties" of the scope, tab : DNS, that once the DHCP-server
has assigned an IP-address the address will be updated in the DNS-server, allowing now
other systems on the network to locate your system :

Once the DHCP-server is configured and authorized and the scope is activated, IP-addresses
will be distributed . You can then view the list of assigned IP-addresses.
