Able to access network resources but can't be ping'd

I have a laptop here running XP Pro that can login to the network, process/run login scripts, access the internet, mail servers, shared drives and other various network resources however the laptop in question cannot be pinged, accessed or otherwise be seen on the network (i.e.: \\Laptop\Share$, \\IP.ADD.RE.SS\Share$; ping IP or host = request timed out) The routing tables look fine, it is authenticating as it should, we've tried two different subnets, releasing and renewing the IP, even used a hard coded IP but the machine could not be pinged or otherwise accessed. I thought maybe the TCP/IP stack might've been corrupted some how so I removed all of the protocols and clients for that NIC however TCP/IP would not disappear from the list. I removed the device from device manager and upon Windows reinstalling the device, after a reboot of course, there was no change. Aside from reimaging the machine, what else do you suggest I try.

Some firewalls block ping.

That's the obvious item.

There are no firewalls on the machine or snffing/DNE drivers loaded. Does have WiFi and 1394 but disabling both in device manager doesn't help.

Then details will help.

In reply to: No

So far, nothing in your gives up the clue.

First off I'd like to say thank you to those brave few who replied; I greatly and sincerely apprecaite everyone's suggestions.
The built-in firwall in XP is enabled but not setup to block ICMP & there is no change when we turn it off.
This is a very strange problem:
If the machine cannot be reached via net use, ping, tracert, \\machine-name\share$ or \\IP\share$ nor are we able to view the event logs remotely etc, how could the network possibly communicate with it? It boggles the mind!
Again, the only problem we have is that we are unable to effectively assist the client remotely. When said client has a problem, we cannot remote into their machine or map a drive to copy files (which happens every so often). However, as far as we and the client are concerned, the machine is functioning as it should.
Can anyone recommend any additional or third-party tools or tests to better diagnose this problem?

Mr. Proffitt - What sort of details do you need/want?

The IP plan for instance.

In reply to: Thx

I can't tell if the IP numbers, netmask are valid on the 2 machines that can't ping each other.

Internal 192.x.x.x and self assigned 169.x.x.x numbers are not internet numbers so you can share that.

I'm at and the netmask is

"When said client has a problem, we cannot remote into their machine or map a drive to copy files (which happens every so often)."

You revealed something here. It's not your machine or you workplace?

Additional Information:
Its a Dell D600 laptop running Windows XP Pro with SP2. We have developed our own image for these machines which include various applications. The machine in question connects to a hard-wired LAN which helps answer the following questions: LAN or WAN? Are there any routers or bridges or maybe even modems involved. Are there smart switches or vLANs or any high end network devices.
We do have high end managed switches and routers on the network but even on a basic ad-hoc network (simple DSL router dishing out IP's via DHCP and a built in hub) the machine is not 'visible'. Its on, it does what it needs to do, I can connect to other machines and resources but nothing can connect to it.
As for IP's: It's not using the standard windows-sanity IP address of 169.254.X.X. It gets a real legit IP of 10.x.x.x, 172.[16-31].x.x, 192.168.x.x or whatever it is that it is connected to.
As for the new Microsoft tool ( I have not had a chance to load it onto the machine as it is not currently in my posession. Will give that a shot to see if there is something funky loaded on the system which we have not yet identified.

That's a good clue. Are you changing the SID?

In reply to: update

With images and in certain situations we also get to change the SID of the machine. Look up SID CHANGER on

You just revealed enough clues that the IT staff may need upgrading of their process. Or that you didn't tell me enough to see if the images are being deployed correctly.
