Win XP SP2 connectivity issue

[tdub]

Dear WinXP gurus:

I have solved a lot of connectivity issues in my time, but this one is over
my head. The machine on which I am typing this message is able to connect
to anything--outbound. However, it will not even respond to a ping from
another host from anywhere. This is a problem since this machine hosts a
shared printer and CD burner for my household. Interestingly enough, when I
ping the machine (by IP address), I can see the packets received count going
up steadily, but nothing is being sent out. This is after I have turned off
both Windows firewall and the Trend Micro firewall.

I used to be able to connect to this machine from other hosts on my home
network. I had some shared folders and shared the printer. However, for
whatever reason, it no longer works. I'm not sure, but it may have broken
down when I installed SP2.

Has anyone seen similar behavior?

Thank you in advance for your assistance
Tim Walker

It still sounds like a firewall, and third party firewall products are
notoriously difficult to 'turn off.' Try:

1. Reboot, F8, and select Safe Mode with Networking.

2. If #1 works, the problem is most likely with the Trend Micro
configuration. If #1 doesn't work, it still may be the firewall - try
completely uninstalling it.
