Cannot ping LAN workstation

[Guest]

Hello,
I have two computers on the same LAN. Both of them are with WinXP SP2.
I turned off the ICF on both computers but I cannot ping from computer A to
B. I can ping from B to A.

How can check where is the problem.
I tried to reset the ICF but no success.
I have no other firewalls installed.
Can I monitor the LAN card to check the problem.
Is there any utility to check this?

Thanks,
Sharon

Sharon,

What is the complete error "cannot ping"?

How did you turn off the ICF? Do you have any other firewalls? What antitrojan
/ antivirus do you have?

Does this fail when you ping both the computer name and the computer IP? If
so, let us know.

OK, first can you ping the A computer itself? Ping 127.0.0.1 and see if that
returns any problems.
No problems? Good. Now Ping the router (typically 192.168.1.1, but could
be different). IF you can Ping the router OK, then check that the default
gateway setting of computer A is the same as for computer B.

Also, check the cabling is secure.

Let us know what happens.

The both computer are in a local network. no routers between them.
I can ping A computer with IP and name
I can ping B computer to 127.0.0.1 but not the LAN address.
I have Symantec antivirus without a firewall.
I have CheckPoint SecureClient (Maybe I need to uninstall it)
I tries to run "nectsh winsock reset". it didn't help.
I stoped the ICF only because this problem.
Comp B can see the all world.

Did you stop the firewall service, or disable the firewall itself? If the
former, you need to make sure that the service is running. Stopping the service
is like blowing a fuse - you are protected by the service stopping, which fails
open so Windows Networking is protected.

For my money, Checkpoint will be, at least, part of the problem. And Symantec
antivirus, even with no packaged firewall, may come with an antiworm component.
An antiworm will act as a firewall and block Windows Networking traffic.

If no help yet, look at "browstat status" and "ipconfig /all" from each
computer, and diagnose the problem. Read this article, and linked articles, and
follow instructions precisely (download browstat!):
