Using Windows 2000 Server

1. Checking for DHCP

1. On the Windows 2000 Server, select Start | Program | Administrative Tools | Computer
Management.
2. Under Services and Applications in the Computer Management Tree you should see DHCP.
3. If DHCP is not present then you need to install the DHCP components for Windows 2000, refer to
the Microsoft documentation.

2a. Creating the Scope
A DHCP scope defines the IP addresses that the DHCP server can issue in response to DHCP
requests. Different scopes may be defined for different types of devices.
1. Select Start | Programs | Administrative Tools | DHCP.
2. Right-click on the server and select New | Scope.
3. The scope creation wizard will be started, click Next.
4. Enter a name and comment for the scope. Click Next.
5. Enter the address range to use, for example from 200.200.200.1 to 200.200.200.15 (remember
the host part cannot be 0).
6. Enter the subnet mask as either the number of bits used or the actual mask, for example 24 is
the same as 255.255.255.0. Click Next.
7. You can specify addresses to be excluded. You can do this either entering a range, eg.
200.200.200.5 to 200.200.200.7 and clicking Add, or just enter a single address and click Add.
Click Next.
• Note: You should exclude the IP Office from this range, as the DHCP Options in the IP
Office should be disabled. This is only a recommendation. You can also accomplish this
by leaving available addresses outside of the scopes range.
8. You can now set the lease time for addresses. If set too large, addresses used by devices no
longer attached will not expire and be available for reuse in a reasonable time, reducing the
number of addresses available for new devices. If set too short it will generate unnecessary traffic
for address renewals. The default is 8 days. Click Next.
9. The wizard gives the option to configure the most common DHCP options. Select Yes and click
Next.
10. Enter the address of the gateway and click Add. You can enter several. Click Next when all are
entered.
11. Enter the DNS domain, eg. savilltech.com and the DNS server addresses. Click Next.
12. Enter the WINS server addresses and click Add. Click Next.
13. You will then be asked if you wish to activate the scope. Select No and click Next.
14. Click Finish to the wizard.
The new scope will now be listed and the status as Inactive.
