Cant ping XP laptop

[Chris Coates]

I have a Dell Laptop loaded with XP Pro. It is a member of an AD domain.
From this laptop I can login, access domain resources, map drives, access
the internet and there are no problems.
However I am unable to connect TO this laptop in anyway from any other
computer on the network, I can not even ping it.

Some additional information:
The laptop is running SP1

The laptop is using DHCP as are hundreds of other PCs and laptops on the
network (which I can ping), so the issue is not a wrong subnet mask of
gateway.

Even machines on the same subnet cannot ping it.

I am trying to ping by IP address not by DNS name, so this is not a name
resolution issue.

I have tried using the network port in the docking station, the one built
into the laptop and also a wireless PCMCIA card. All of which connect to the
network but none of which can I ping to. So this is not a NIC hardware, or
driver or issue since all 3 use different drivers. (I did upgrade the
drivers and this made no difference.)

There are no errors in the event log related to network.

Device manager shows that the Network cards are working correctly.

I do not have a firewall installed

I suspect this is something as simple as an unnoticed check box, but I have
not been able to come up with anything.

Any suggestions are appreciated.

Thanks

Do you have the internal firewall that comes with windows xp active?

Ideas:

- Can you ping itself, e.g. "ping localhost", or "ping 127.0.0.1"
- are you *sure* there is no firewall turned on?
- i wonder why the docking station has a different ip adress than the
laptop which is different from the PCMCIA card... this seems strange to
me. What are these addresses? You have three LAN card in operation?
- when you run "ipconfig /all" do you see any surprises?

 

[Chris Coates]

No, the internal firewall is not active.
Any other ideas?

I can ping the local host.
I double checked and the built-in fire wall is not on and I have never
installed a firewall on this laptop.
I normally have the built in card in the laptop disabled (I did recently
reenable it for troubleshooting this issue but disables it again when that
failed to help) and just use either the docking station or the wireless. I
enabled the built in and everything looks fine. Which ever card is plugged
in gets a IP address and locates the DNS and WINS servers. I did a IPCONFIG
/ release and rebooted with the LAN cable in the docking station and then
switched to the built in and did it again and both picked up an address.

I just spent three days trying to solve this problem with
IBM and Microsoft tech support. Here is what finally
worked:

Open explorer and select "My Computer". Click on Tools,
Folder Options, View. Go to the last item in the
list, "Use simple file sharing (Recommended)" and de-
select it.

That might work.

Well .. since you ruled out everything ... and except for the fact that
you can't ping from outside, the machine is functional (true?) ... maybe
time to a) hire a network guru, or b) forget about it.

 

[Rob Schneider]

Gee, that's obvious! (gosh, I wonder how that would have an affect
on low level networking like the ping ... learn something every day...
will be interesting to see if that fixes this!)

I tried it, but it did not help.
Any other suggestions?
