Norton Internet Security 2004

Why can I not ping my own IP address when I have NIS switched on. I have 2 computer linked with an Ethernet crossover cable. I can happily ping my own IP address with NIS switched off (I have set up a static IP in the LAN connections). However when I re-enable NIS. I can only ping the other computer (but not my own).

Very weird.

You could check NIS to see whether it is configured to block any specific IP addresses (ie your own ip address or computer name/domain). Don't ask me where the settings are though because I steer clear of Norton.

Is your Windows Firewall (ICF) on or off? Try it without that enabled to see if that makes a difference. Also, are you trying to run any other firewall/av apps in addition to Norton on the same machine? Like Paul has indicated, it is almost certainly a setting somewhere within NIS that is causing this (and also proven by the fact that this doesn't occur when you switch Norton off). Are you experiencing any other network problems? How do you connect to the Internet, if at all, with the machines in question?

Eventually found the Norton rule that was stopping this. I reset all the statistics within NIS, ran the ping command then was able to work out which rule was preventing this.

Thank God for Norton, keeps all our minds sharp

Glad to hear you're up and running again. It would be great if you could post the exact location of the setting you changed, as it could very well help someone in the future who is having the same problem. Also, did you need to deactivate ICF (Windows Firewall) to get it to work?

Deleted the rule within

Settings---->Personal Firewall---->Advanced---->General--->Inbound ICMP request
