Configure a DHCP Server – Lab

You are a network technician for a small corporate network. You want to use DHCP to provide TCP/IP address information to the workstations in the network. Because you already have a Windows Server 2008 R2 server (named Server) installed and running in the Network Closet rack, you decide to use it as the DHCP server. After installing the DHCP server role, you are now ready to configure an IPv4 scope.

Your task in this lab is to do the following:

• On the computer in the Networking Closet (named Server), create a DHCP IPv4 scope with the following parameters:
  • Scope name: Subnet
  • Address range: 168.0.20 to 192.168.0.50
  • Subnet mask: 255.255.0
  • Exclusions and delays: Do not set
  • Lease duration: Accept the default duration
  • Scope option for the Router (default gateway): 168.0.5
  • Parent domain: Do not set
  • Scope option for DNS servers: 28.56.108
  • WINS Servers: Do not set
• On Server, activate the Subnet

On the laptop (named Sup-lap) in the Support Office, confirm the DHCP scope settings by configuring the local area connection to obtain its IP and DNS addresses automatically from the DHCP server.
