Can't self-ping but network works??

[Fred Marshall]

I just configured a small LAN and had a heck of a time because one of the XP
computers wouldn't ping it's own IP address. This is a LAN using a Linksys
router. Internet access was always solid but the connectivity over the LAN
was problematic.

So, I'd check the XP machine by pinging itself.
127.0.0.1 worked
192.168.2.xxx did not work - ever.

After doing all the normal stack repairs, etc. the ping still didn't work.
But the workgroup finally came alive.

Any insights?

Thanks,

Fred

I would check the firewall first.

When a computer can't ping its own IP address,the problem is probably
caused by a firewall program (Norton, McAfee, PC-cillin, ZoneAlarm,
etc) that's incorrectly installed or incorrectly configured.

If you've installed a firewall program, make sure to disable XP's
built-in Windows Firewall. Running both is likely to cause problems.

To see if a firewall program is causing the problem, enable the
Windows Firewall, then uninstall (don't just disable) the firewall
program. Some firewall programs don't uninstall cleanly, so go to
Start | Run | Msconfig | Startup and disable any firewall remnants.
Then reboot and try the ping again.
