1 Configuring DHCP

Dynamic Host Configuration Protocol is used to assign address to network devices. Administrators can configure DHCP to provide other networking information to end devices, necessary for proper network function.

1.1 Installing the DHCP Role 1. Open the Windows W2k16-DCA server by clicking the icon in the topology. Click “PC > Send

CTRL+ALT+DEL”.

2. Type P@ssw0rd as the administrator password and hit “Enter”.

4


3. On the “Server Manager – Dashboard” navigate to “Manage > Add Roles and Features”.





4. On the “Before You Begin” page, click “Next”.

5. On the “Installation Type” page, leave the defaults and click “Next”.

13






6. On the “Server Selection” page, click “Next”.

7. On the “Server Roles” page, place a check mark next to DHCP Server and click "Next".

14


8. On the “Features” page, click “Next”.





9. On the “DHCP Server” page, read the information on DHCP and click “Next”.

15


10. On the “Confirmation” page, click “Install”.

11. On the “Results” page, click “Close”.





12. On the “Server Manager – Dashboard”, click the yellow alert at the top of the page and select“Complete DHCP configuration”.

16


13. On the “Description” page, click “Next”.

14. On the “Authorization” page, click “Commit” and “Close”.





17


39. On the “Server Manager – Dashboard”, navigate to “Tools > DHCP”.

40. Expand the DHCP window by clicking the square in the top right.

41. Adjust the size of the side pane by hovering over the vertical line, hold the left mouse buttondown and drag to the right.





1.2 DHCP Scopes

1. On the “DHCP Management” window, expand W2k16-DCA and expand IPv4 by clicking thetriangle to the left of each.

2. Right click on IPv4 and select “New Scope”.

18


3. On the “Welcome to the New Scope Wizard” window, click “Next”.





4. On the “Scope Name” page, type Workstations-2 and for the description type LAN. Click “Next”.

19


5. On the “IP Address Range” page, type the following and hit “Next”.Start IP address: 10.0.0.51End IP address: 10.0.0.99Length: 24Subnet mask: 255.255.255.0Click “Next”.





6. On the “Add Exclusions” page, type the following and hit “Add”.Start IP address: 10.0.0.51End IP address: 10.0.0.55Click “Next”.

20


7. On the “Lease Duration” page, leave the default of 8 days and click “Next”.





8. On the “Configure DHCP Options” page, leave the default of YES and click “Next”.

21


9. On the “Default Gateway” page, type 10.0.0.1 and click “Add”. Click “Next”.





10. On the “Domain Name and DNS Servers” page, leave the defaults and click “Next”.

22


11. On the “WINS Server” page, click “Next”.





12. On the “Activate Scope” page, click “Next” and click “Finish”.

13. DHCP is essentially configured at this point and will assign addresses in the range we set.

23






2 DHCP Options

Computers are not the only devices that use DHCP. It might be necessary to provide additional information to other end devices. These parameters are set as options.

2.1 Setting options

1. On the “DHCP Management” window, expand “Scope [10.0.0.0], left click, then right click“Scope Options” and select “Configure Options”.

2. This list is used to provide additional information dynamically to devices on the network. Clickon “003 Router”. This is the default gateway setting we set while installing the DHCP role.

24






3. Scroll down and click on “006 DNS Servers”. This provides the address of the DNS server toclients requesting DHCP. You can add multiple DNS server addresses to this list.

4. Another common option you might see is the “WINS/NetBIOS” server setting.

5. Close the “Scope Options” window.

25






2.2 Adding Options

1. We can also add options. Right click IPv4, and select “Set Predefined Options”.

2. Click the “Add” button.

3. Type Phone Configuration Files as the name, change the Data Type to “IP Address” and add 150for the code. Click “OK”.

26






4. We would then type in the address of the Phone Management Server. Click “Cancel”

5. This option sets it so that Phones receiving DHCP on this LAN will also receive the IP

27


address of the server to contact for configuration files.





3 DHCP Reservations

DHCP Reservations are a means to always provide the same address to a device without assigning a static address.

3.1 Configuring Reservations

1. On the “DHCP Management” window, left click then right click on “Reservations” and select“New Reservation”.

2. Open a console to the Win10-B machine. Log on using the password Train1ng$.

3. In the searhc bar type cmd.

28






4. Select the “Command Prompt” option from the search result.

5. On the command prompt, type ipconfig /all and hit “Enter”.

6. The Physical Address is the Layer 2 MAC address associated with the NIC on this machine.Write down this MAC address.

29






7. Return to the W2k16-DCA machine and add this information to the “New Reservation”window.Reservation name: Windows10-BIP address: 10.0.0.81MAC address: 005056B5378B (remove the hyphens) Click “Add” and click “Close”.

30


8. Open a console to the WIN10-B machine. On the command prompt, type ipconfig /release andhit “Enter”.





9. Type ipconfig /renew and hit “Enter”. The WIN10-B will receive the new reservation address.

Unless specific rules are set up, DHCP and clients operate on a first come first serve basis. The first server to respond to an address request will fulfill the request. Rogue DHCP servers or improperly configured DHCP servers can issue incorrect addressing and cause network complications.

Take any screenshots and notes required by your instructor and click “I’M DONE” at the top of the topology page. You may complete this lab as many times as you wish by making a new reservation.
