Question: Working with the DHCP Client Time Required: 10 minutes Objective: Use ipconfig to work with your DHCP client. Required Tools and Equipment: Net-XX, a configured DHCP server on the network Description: In this project, you change your IP settings to use DHCP and then see how to work with DHCP by using ipconfig.

1. If necessary, log on to your computer as Net Admin.

2. Right-click Start and click Network Connections. Right-click Ethernet0 and click Properties to open the Ethernet0 Properties dialog box.

3. Click Internet Protocol Version 4 (TCP/IPv4) and click Properties. If your IP address settings were set manually in Hands-On Project 5-1, write these settings on the following lines. At the end of this project, you set your IP address again by using these settings.

4. Click Obtain an IP address automatically. Click OK and then Close.

5. Open a command prompt window, if necessary. Type ipconfig /all and press Enter to view detailed IP configuration information. Under Ethernet adapter Ethernet0, you see information about DHCP, including its status (enabled or not), the DHCP server's IP address, and lease information.

6. Occasionally, you might need to force your computer to renew its lease (for example, if changes are made on the DHCP server and you need to get the newest IP configuration). To renew a DHCP lease, type ipconfig /renew and press Enter. Display your detailed IP configuration again to see that the lease information has changed.

7. To release your IP address configuration, type ipconfig /release and press Enter. This command's output shows that your IP configuration has been deleted. To request a new IP address configuration, type ipconfig /renew and press Enter. (Note that you might not get the same IP address you had before.) Using these commands can help you troubleshoot DHCP-related problems.

8. Close the command prompt window, and set your IP configuration to the values you wrote down in Step 3.
