The other computer CANNOT ping my IP of 10.1.1.130. Also all other computers on the network have no ping problems suggesting that the router setting are not blocking packets and it must be an internal computer setting. I have tried disabling the windows firewall completely, restoring the windows firewall default settings and disabling the routers firewall and none of these made any difference to the cause. I have made sure that the "allow incoming echo request" box is ticked under the firewall settings. I have run the "RegCure" program and repaired all the scanned problems, still no go. I have no problem browsing the web, it's just that I cannot set up the computer for home networking or in that case any networking places.

I have had previous third party antivirus software including McFee, Windows One Care and Kaspersky. All these programs have been uninstalled from the computer and no signs of them exist when running a search. Is it possible that their previous firewall setting may still exist within windows? I have been trying to fix this problem for a long time now searching all the possibilities on the net but can't find a solution.

So as I mentioned earlier the problem seems to be a setting applied within this computer as all other computers using the router have no difficulty. If you could provide any feedback it would be much appreciated and would stop me from pulling my hair out!!!

hello,

even if you have the firewall disabled, i think you have to specifically enable icmp messages on your machine. i think this is in the network connections dialog under advanced or what-not..........i think i'm correct

i'm not around windows machines much except occasionally at work.
hope this helps

You may want to make sure that there is not an IPSec policy in place, it may have been put in to circumvent an XP TCP/IP vulnerability. Below is a link that talks about.
