[Inderjeet]

I have windows 2000 professional computers and also have
windows 95/98/XP computers in my network. Onle computer
which is acting as a node for some applications is workin
fine and i can access it from any other computers from
network but, the only thing i cannot do is i cannot PING
the computer from any other computer in network.

Rest everything is working fine and i have checked for the
IPSEC policy and that is Disabled on the system under
Local security policy.

Turn off your internal firewalls while testing, especially those
that are bundled with your virus scanner.

But i donot have any Firewall enabled anywhere. I am using
Symantec client and every computer is using the same
client with same configuration

- Start a DOS prompt on the problem PC (or a Command Prompt
if it is a Win2000 PC).
- Type this command: ipconfig /all > c:\ip.txt
- Do the same thing on one of the other machines.
- Post the contents of both files in your next reply.

In your reply you first say:

This is the ip.txt for the computer which is not being pinged and then you say:
this is the ip.txt of the computer from where i was pinging the above

computer

There is an inherent contradiction in what you write. I will now
assume that you meant to say:

This is the ip.txt for the computer which is being pinged and
this is the ip.txt of the computer from where i was pinging the above

computer

I will also give the PCs names. I will call the Win2000 PC the "pingee",
and the Win98 machine the "pinger".

- The pinger's IP address is 10.12.1.43.
- The pingee's IP address is 10.12.1.9.

The addresses are OK. I would now do this:
- Remove one of the two network adapters from the pinger.
You need to keep things simple while testing.
- Force both adapters to run at 10 MBits/s half duplex.
- Make the network icon visible for the pingee, and watch
the byte counter when pinging.
- Install Ethereal on both machines, and watch what happens to
to packets.

I know that you say that you do not have a firewall. On the other
hand I also know that in similar posts I read in the past, there was
almost always a firewall involved, unknown to the poster. If there
is a faint possibility of there being some firewall function embedded
in your Symantec software then you might save yourself a great
deal of time if you dealt with this issue first, until you were absolutely
sure that it does not play a part. Do not rely on the fact that other
machines work: Dig as deep as you can!
