Firewall issue with ping command

Written on January 11th, 2010 by viliyana89one shout

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.

Remote connection to application

When an expert attempts to connect to a novice’s computer, the expert may receive the following error message: ” A Remote Assistance connection could not be established. You may want to check for network issues or determine if the invitation expired or was cancelled by the person who sent it.”
This problem can occur if the Internet Connection Firewall has been enabled after the Remote Assistance invitation was created. To resolve this problem, we should either create a new Remote Assistance invitation while ICF is enabled, and then send the new invitation to the expert; or we should disable the Internet Connection Firewall while the expert attempts to establish the Remote Assistance invitation; or restart the novice’s computer, and then have the expert establish the Remote Assistance session.
