Your computer is running Windows XP Professional with Service Pack 1 installed without the Internet Connection Firewall or ICF enabled. You frequently use the Remote Desktop feature to connect to your home computer. A couple of days ago, all computers at your office were upgraded to Service Pack 2 versions. After the upgrade, you are not able to connect to your home computer. Which of the following could fix the problem?
Explanation
Answer: B - ICF is enabled by default when Service Pack 2 is installed. ICF will block Remote Desktop. To be able to connect the home computer, you should add Remote Desktop to the list of Windows Firewall exceptions.
Key Takeaway: Windows XP's Internet Connection Firewall (ICF) protects your network against undesired incoming traffic from the Internet. It creates a protective barrier between your network and the Internet, only passing through traffic that you've requested. This is enabled by default when Service Pack 2 is installed. To enable ICF on an Internet connection, open the Network Connections folder, right click the desired connection, and click Properties. To add Remote Desktop to the list of Windows Firewall exceptions, choose Control Panel, open the Security Center utility, select Windows Firewall, open the Exceptions tab, and click the Add Program button. In the Add a Program dialog, click Browse and locate the application you wish to allow.
