Practice 2: Connect a Windows XP computer to a network with a Dynamic Host Configuration Protocol (DHCP) server. Verify that the Windows XP Professional computer obtains its TCP/IP configuration from the DHCP server. Then use Ipconfig.exe to examine, release, and renew DHCP leases on the Windows XP Professional computer. Practice 3: Familiarize yourself with the other tools available for troubleshooting network connections such as Arp.exe, Hostname.exe, Ipconfig.exe, Ping.exe, Pathping.exe, Tracert.exe, Netstat.exe, and Route.exe. Practice 4: Configure a static TCP/IP address for a client computer that normally relies on DHCP-assigned Internet Protocol (IP) addresses. Practice 5: Use the Nslookup.exe utility to identify the IP addresses for http:// www.microsoft.com. Practice 6: Edit the HOSTS file in the %windir%\system32\drivers\etc directory so that the domain name http://www.microsoft.com resolves to the IP address 127.0.0.1. Save the HOSTS file, and use the command ping www.microsoft.com to verify that this domain name resolves to the IP address 127.0.0.1. Edit the HOSTS file again, remove the new entry, and save the file.

Practice 1: Create a dial-up connection to an Internet service provider (ISP). After this connection is working properly, configure Internet Connection Sharing (ICS) to allow multiple computers to access the Internet across a single link. Practice 2: If you have a VPN server available, establish a VPN tunnel. Configure this connection with ICS to allow multiple computers to use the VPN simultaneously. Practice 1: Configure offline Web pages to store several Web sites offline. Open the Synchronize dialog box, and adjust the properties to automatically download these sites at a specific time. After this time has passed, disconnect from the network and attempt to access one of the offline Web sites. Practice 2: Press Ctrl+H to open the history toolbar. Notice that all sites visited in the last several weeks are available for recall. Practice 3: Use the Internet Options dialog box to clear your temporary Internet files and history. This helps to protect your privacy if other people have access to your computer. Practice 4: Using the Security tab of the Internet Options dialog box, compare the security settings for the Internet and Trusted Sites zones. Consider how they differ, and how that improves the security of your computer.

Practice 5: Using the Privacy tab of the Internet Options dialog, examine the settings for each of the six privacy levels. Temporarily set your privacy level to Block All Cookies, and then visit several of your favorite Web sites. Consider how your user experience was affected. Afterwards, set the privacy level to its original setting. Practice 1: If IIS was not installed with Windows XP, install it from Add/ Remove Windows Components in Control Panel. Familiarize yourself with the different IIS components available for installation. Practice 2: Edit the application configuration to remove unused script mappings. Although this does not change the site s existing functionality, it does dramatically reduce the risk of security vulnerabilities. Practice 3: Add a virtual directory, and disable anonymous access to the virtual directory. Access the virtual directory using Internet Explorer and notice that you are prompted for authentication. Provide your user name and password, and verify that you have access. Practice 4: Modify NTFS file permissions for Web content within the IIS home directory. Notice how removing Read file permissions for the IUSR_computername account affects your ability to anonymously access files. Practice 5: Install an IIS security hot fixes if any are available.

Configure, manage, and implement Internet Information Services (IIS).
