Scenario
You must now deploy DHCP and IPAM in the A. Datum forest to support your DHCP and IPAM implementation strategies.
The main tasks for this exercise are as follows:
1. Install the DHCP Server role.
2. Configure a DHCP failover relationship.
3. Install IPAM.
4. Configure Group Policy Object (GPO) Settings.
5. Configure IP management server discovery.
6. Configure managed servers.
7. Configure and verify a DHCP scope with IPAM.
8. Configure IP address blocks, record IP addresses, and create DHCP reservations.
Task 1: Install the DHCP Server role
1. If necessary, sign in to LON-SVR1 as Adatum\Administrator with a password of Pa$$w0rd.
2. Use Server Manager to install the DHCP Server role.
3. Complete the DHCP post install configuration.
Task 2: Configure a DHCP failover relationship 1. Switch to LON-DC1.
2. If necessary, sign in to LON-DC1 as Adatum\Administrator with a password of Pa$$w0rd.
3. In Server Manager, click Tools, and then in the drop-down list box, click DHCP.
4. In the DHCP console, launch the Configuration Failover Wizard.
5. Configure failover replication with the following settings:
o Partner server: 172.16.0.11
o Relationship Name: Adatum DHCP Failover o Maximum Client Lead Time: 15 minutes o Mode: Load balance

o Load Balance Percentage: 50%
o State Switchover Interval: 45 minutes
o Message authentication shared secret: Pa$$w0rd 6. Complete the Configuration Failover Wizard.
7. Switch back to LON-SVR1, open the DHCP console, and note that the IPv4 node is active, and that the Adatum scope is configured.
8. Close the DHCP console on both LON-SVR1 and LON-DC1.
Task 3: Install IPAM
1. If necessary, sign in to LON-SVR2 as Adatum\Administrator with a password of Pa$$w0rd.
2. In Server Manager, use the Add Roles and Features Wizard to add the IP Address Management (IPAM) Server feature and all required supporting features.
Task 4: Configure Group Policy Object (GPO) Settings 1. In the Server Manager navigation pane, click IPAM.
2. In the IPAM Overview pane, provision the IPAM server by using Group Policy.
3. Enter IPAM as the GPO name prefix, and provision IPAM.
Task 5: Configure IP management server discovery
• In the IPAM Overview pane, configure server discovery for the Adatum domain, and then start the server discovery process.
Note: Discovery may take 5 to 10 minutes to run. The yellow bar indicates when discovery is complete.
Task 6: Configure managed servers
1. In the IPAM Overview pane, add the servers to be managed.
2. Verify that IPAM access is currently blocked.
3. Use Windows PowerShell to grant the IPAM server permission to manage LON-DC1 by using the following command:
Invoke-IpamGpoProvisioning –Domain Adatum.com –GpoPrefixName IPAM
–IpamServerFqdn LON-SVR2.adatum.com
–DelegatedGpoUser Administrator
4. Set the manageability status to Managed for both servers.
5. Switch to LON-DC1.
6. Force the update of Group Policy.
7. Verify the IPAM GPOs were applied.
8. Switch to LON-SVR1.
9. Force the update of Group Policy.
10. Verify that the IPAM_DHCP GPO has been applied.

11. Switch back to LON-SVR2 and refresh the server access status and IPv4 view.
12. In the IPAM Overview pane, retrieve data from the managed server.
Note: This action may take five minutes or more to complete.
Task 7: Configure and verify a DHCP scope with IPAM 1. Switch to LON-SVR2.
2. Use IPAM to create a DHCP IPv4 scope for the Paris Office by using the following settings:
o Start IP address: 172.32.32.2 o End IP address: 172.32.32.200 o Subnet mask: 255.255.224.0 o Router: 172.32.32.1
o DNS Server: 172.32.32.2 3. Verify the new scope in IPAM.
4. Verify the new scope in LON-DC1.
5. On LON-SVR2, use IPAM to configure failover for the Paris Office scope by using the existing failover relationship between LON-DC1 and LON-SVR1.
Task 8: Configure IP address blocks, record IP addresses, and create DHCP reservations 1. On LON-SVR2, in Server Manager, in the IPAM pane, click IP address Blocks.
2. In the Current view list, click IP Address Ranges. Note that due to DHCP failover, 172.32.32.0 is listed twice.
3. Right-click the 172.32.32.0/19 range for lon-dc1.adatum.com, and then click Edit IP Address Range.
4. In the Edit IP Address Range dialog box, click Reservations.
5. In the Reservation text box, type 172.32.32.2, and then click Add.
6. In the Edit IP Address Range dialog box, click OK.
Results: After completing this exercise, you will have deployed DHCP and IPAM to support your proposals.
Task: To prepare for the next module
When you finish the lab, revert the virtual machines to their initial state. To do this, perform the following steps:
1. On the host computer, start Microsoft Hyper-V Manager.
2. In the Virtual Machines list, right-click 20413C-LON-DC1, and then click Revert.
3. In the Revert Virtual Machine dialog box, click Revert.
4. Repeat steps 2 through 3 for 20413C-LON-SVR1 and 20413C-LON-SVR2.
