Does XP SP2 block ICMP? was created by Raghupyapili
Might be a basic question, but is bothering me for past many days, I'm not able to get the IP address in command prompt (It literally takes me back to the command prompt if we go for IPCONFIG)in Win XP SP2, not even able to ping websites even if i'm able to open them, heard that SP2 blocks ICMP, is it true, Please clarify this?

Windows XP SP2 come with a firewall, which as I understand, in order to cover for the multiple vulnerabilities of the OS, is configured with some aggresive settings. But by default, outgoing ICMP packets are not blocked. There has to be some other reason for you not being able to ping internet hosts, try doing a "tracert" instead -I believe windows tracert uses ICMP, so you'll see if an other node between you and the targeted host blocks ICMP.

Thanks for this, i forgotr to mention one thing here , even if we disable the SP2 firewall this happens but once we uninstall the same we would get the router IP (I mean Linksys) do we need to install the windows patch that is on the Microsoft site?

It is always good to install the latest patches through the microsoft update service, but I don't believe it has anything to do with this problem.
Although I did not understand what you mean by saying that you can not get the PC's IP address (i.e. through the ipconfig) and that if you disable the firewall you get the router's IP address, I don't think it is a matter of windows. Perhaps your Linksys router is configured to drop ICMP packets?
