Windows 2000 DHCP Installation and Configuration
This exercise involves configuring a Windows 2000 DHCP server to allocate
addresses to an IP network. Options are also configured to enable Mitel IP
Phones to work correctly – At this point it is worth noting that a PC that is given
Mitel IP Phone options will simply ignore them and just utilize the standard
options allocated, IP Address, Subnet mask etc.
You will firstly configure the DHCP server, then set the other PC on you network
to obtain an IP address automatically from the DHCP server.
ON THE DHCP SERVER
1. From the start menu select Programs / Administrative Tools / DHCP
2. Right Click on server address in the Tree window and select New Scope
3. When the New Scope Wizard window appears, click on next
4. Enter a name (use your Group Number) and description for the new scope
and click on next
5. Enter the IP address range of the new scope – Remember that this is the
Range for the ‘Default VLAN’, the ‘Voice VLAN’ range is on the 3300!
The Start Address will be 192.168.x.50 where x is the 3rd Octet in
the ‘Default VLAN’ network address
The End IP address will be 192.168.x 75
Set the Subnet mask to 255.255.255.0 and click on next
6. Click on Next on the Add Exclusions window and the Lease Duration
7. On the Configure DHCP Options window select the No, I will configure
these options later button and click on Next and then Finish.
8. To add the user assigned options right click on the server address in the
Tree window and select Set Predefined Options – These Predefined
options will provide the MITEL IP Sets with the information that they need
9. Click on Add
10. Enter the Name, Data type and code for the user defined options as
11. To configure the Server options, i.e. those options that apply to all scopes,
right click on the ser
12. Tick those options required i.e. 128, 129, 130, 132 and 133, and enter the
128 = TFTP server address ( IP address of RTC card)
129 = RTC card IP address
130 = MITEL IP PHONE
132 = VLAN ID 0x2 (hex value)
133 = Priority 0x6 (hex value)
13. Then click on Apply
14. The Server Options window should look like this
15. To add the scope options, i.e. those options that only apply to an
individual scope, open the tree for the scope and click on the Scope
16. Select those options that apply to the scope only i.e. 3, and enter the
correct value and click apply. 3 = Router address and should be the
default gateway address for the scope.
17. The options window should now look like this
18. To activate the new scope, right click on the scope folder in the Tree
window and select Activate
19. The red dot on the scope folder should go green.
ON THE CLIENT PC
1. Click on the Start button and select Settings, then ‘Network and Dial-UP
Connections’. The Dialog box should open
2. ‘Right-Click’ on your LAN Connection icon and choose Properties
3. In the dialog box that appears, scroll down to Internet Protocol (TCP/IP),
highlight and click on Properties
4. In the dialog box that appears (as below), select ‘Obtain and IP address
automatically’. (If your DHCP server is allocating a DNS address, then
select the automatic option for that as well, otherwise leave as configured)
5. Click on OK to close the Dialog box, then OK on the remaining window to
SAVE the settings.
6. From a Command windows (Start, Run, Type CMD and click on OK)
7. Use IPCONFIG to see you configuration, Use IPConfig /Release to ‘give-
up’ the IP address. IPConfig /Renew to get a new one.
8. Try ‘Pinging’ the DHCP Server
9. Check the Leases given out on the DHCP Server.
