You have just set up a new Windows XP Professional computer at home. The computer is always connected to the internet via an ADSL modem. The computer is configured to have a static IP address assigned by your Internet Service Provider. You enable the Internet connection Firewall on the ADSL connection. You use the Ping command on your office computer to try to connect to your home computer. However, you receive the following error message: “Request timed out.”
The ping command sends a series of ICMP echo requests to the specified computer. However, the ICMP echo requests are being dropped by the firewall and are therefore not reaching the specified computer. We need to configure the firewall to allow the ICMP echo requests so that they can pass to the specified computer.

You are the desktop administrator for the Graphic Design Institute. You have just deployed new Windows XP Professional computers to all graphic designers. Each computer has a built-in tape drive for data backups. The graphic designers need to back up their own data to the tape drive. You add all graphic designers’ user accounts administrator members of the Backup Operators group on their computers. Then you instruct the graphic designers to create a full backup of all their data every Monday morning. The graphic designers need to back up all of their data once a week. They also need to back up all the changes since the last full backup. The graphic designers want to use a backup method that allows them to recover their data as quickly as possible. You should advice graphic designer to perform a normal backup every Monday. Create an Incremental backup for Tuesday, Wednesday, Thursday, and Friday. A Differential back up only backs up files and folders that are marked as having been altered since the last full backup but does not clear these markers. These markers are called archive bits. Thus, if we performed two differential backups on a file that has been altered since the last full back but not since the last differential backup, the file would be backed up on both occasions. This provides the quickest recovery method as we would have to restore only the most recent full backup and the most recent differential backup.

You have just installed Windows XP Professional on a portable computer for a user. The computer is configured to have a modem and Ethernet PC card. At the office, the user uses his computer in a docking station. At home, he uses his computer in an undocked state by using the power adapter. This user travels to customer locations frequently. While traveling, he creates and edits documents. When he returns from a customer location, he inform you that the battery power in his computer has not lasted as long as he would like. You need to configure user’s portable computer to conserve battery power for his sales trips. You should create a new hardware profile named Remote. Use Device Manager to disable the modem and Ethernet PC card devices for this hardware profile. A hardware profile is used to store the configuration settings for a set of devices and services that are used on a computer. In Windows XP Professional you can create different hardware profiles to meet a user’s needs in different situations. The user can then choose the appropriate profile the Windows XP Professional should load when starting the computer. To ensure the optimal performance in different networking environments, we should create different hardware profiles that the users can choose from under different network environments. In this scenario we should create a profile that has the modem and Ethernet card disabled to save the battery resources used to power these cards. The user can then choose this profile when he is visiting client sites.
