| Objectives Configure and troubleshoot the TCP/IP protocol. Connect to computers by using dial-up networking. Connect to computers by using a virtual private network (VPN) connection. Create a dial-up connection to connect to a remote access server. Connect to the Internet by using dial-up networking. Configure and troubleshoot Internet Connection Sharing (ICS). Dial-up networking (DUN) enables a Windows XP computer to connect to another single computer, a private network, or to the Internet through a modem or other adapter. This same connection can then be shared with other computers on the network. You are expected to know how to configure and troubleshoot all types of connections.
Connect to resources by using Internet Explorer. Users are likely to rely on Internet Explorer for their Internet experience. However, users may also need to connect to other resources and prefer using Internet Explorer as a common interface. You therefore are expected to also know how to connect to files, shared folders, Web folders, and other network elements.
Configure, manage, and implement Internet Information Services (IIS). Configure, manage, and troubleshoot Remote Desktop and Remote Assistance. Both Remote Assistance and Remote Desktop applications use RDP, but that's where their similarity ends. This objective focuses on knowing the difference between the two applications, their situational usage, and management.
| Configure, manage, and troubleshoot an Internet Connection Firewall (ICF). |
Windows Firewall, also known as Internet Connection Firewall (ICF), provides some basic protection from unauthorized access to the computer. You will be expected to know the capabilities of Windows Firewall, how to configure it, and how to troubleshoot access errors.

Study Strategies Transmission Control Protocol/Internet Protocol (TCP/IP) provides the basic connectivity for Windows XP to communicate with other computers. You should practice troubleshooting TCP/IP on a network with at least three segments. Place a computer at one end of the network. Place a server at the other end. Change an IP address so that it is incorrect. Test connectivity between the two computers. Use the various TCP/IP troubleshooting tools. You should have a thorough understanding of how to subnet Class A, B, and C addresses so that there are sufficient addresses per segment for the required physical segments on the network. This will take practice with paper and a pencil. To prepare for the dial-up section of the exam, you should configure a network server that provides remote connections via dial-up and virtual private networking (VPN), and a Windows XP Professional computer. You should have two phone lines available to you and an ISP. Using these resources, you can configure and test the dial-up connections under various configurations. For the exam, you are expected to know how to use Internet Explorer to correctly connect to local and network resources. Prepare for this by using at least two computers configured in a workgroup or domain network and use Internet Explorer to open files and printers. The skills you need for Internet Information Services (IIS) require you to learn how to install and configure IIS and a website on a Windows XP Professional computer. You need an additional computer to test connectivity to the website you create. Using two different Windows XP Professional computers and Outlook Express, you should be able to configure and connect to a Remote Desktop session; plus you should be able to request and receive Remote Assistance. Test using email requests. You need to understand how to configure Windows Firewall under Service Pack 2 (SP2), and the enhancements made from Internet Connection Firewall (ICF) that originally came with Windows XP Professional. This requires you to have a Windows XP Professional computer, review how to configure ICF, and then upgrade the computer with SP2 and configure Windows Firewall, noting the new features.
