WIndows XP - can't ping anything

I have a strange problem with a Windows XP Professional SP3 PC. The PC is unable to ping any hosts either local or internet-based and reports 'Destination Host Unreachable'. The PC is able to browse the internet, send emails and connect to local devices such as routers that it cannot ping.

I have disabled the local (McAfee) firewall to no effect - other PC's in the same office use the same firewall with the same rules and have no problem.

The network settings are derived from DHCP which is fine for other PC's. I have tried manually setting the details to no effect, I have also tried a different address.

I have also tried resetting the TCP stack, clearing the ARP cache, running SFC /scannow and doing a Windows XP repair - all to no avail.

The network card is on the latest driver I can find - it's a Dell-suplied GVC Realtek.

I'm really scratching my head here. The PC is on a domain and, although it can login / be joined and removed from the domain, it won't process Group Policy as it can't locate a DC - I think because it can't ping anything.

Hope someone has an idea - my next port of call will be a complete rebuild but that seems like overkill.

was it removed or deactivated from the domain controller?

Another thing to check is Windows Firewall is off?

Another check is that DHCP is active and it is not a static IP or DNS?

Did you Ping the following IP 127.0.0.1? You can ping this with the machine not connected to anything. It will prove your NIC card as well as your drivers are working right with windows.

It has been removed and rejoined to the domain. Windows firewall is definitely off. DHCP is definitely active and it is not a static address, although I have tried this and it made no difference.

Danjah - it can ping the local address - both 127.0.0.1 and the DHCP assigned address.

ipconfig.  does that show the correct ip/subnet/gateway/dns info?

Try ipconfig /dnsflush

Does it have a static ip address?

I have seen this behavior with computers with static ip address and conflicting with another machine.

"I have also tried resetting the TCP stack"

Try resetting the firewall as well....

netsh firewall reset

Reboot, and turn it off again if needed.....

Also, when I have a machine that wont respond to pings, I will also pull out the nic from the Device Manager, perform the 3 reset commands, and reboot, and reinstall the NIC with teh latest drivers from the Mfgr.

Might help, as it resets alot of the info in the registry....

Was it ever able to ping?  when did it stop pinging?  what happened the day it stopped pinging that could have possibly caused the problem?

List your ipconfig for us: Run > CMD > IPConfig and also paste in your environmental variables > Path

BeehiveITAuthor Commented:
Pretty sure the IPconfig is absolutely normal since the address is being given out by DHCP which is fine for other PC's in the same office. Also, I  have tried setting up the IP manually using the address given by DHCP and using a completely different address and it still doesn't work.

Wontl have access to the PC again until Friday but will post IPConfig and Path details.

losqadas: not sure when it ever stopped being able to ping. One thing I haven't tested is if it is running ping from the correct location. Long shot but worth a try.

Have you tried removing McAfee fully and test?
Use its removal tool

johnb6767Commented:
Any chance there might be some mcafee components behind (even though it is disabled)? I would uninstall it for testing....

Optoma: Will try uninstalling McAfee and see if that makes a difference. Can't do that until tomorrow though.

You can try doing a WIN SOCK Repair. Here's a tool that would help you with that.

Im sorry if these have been asked but its 2am here and this question interests me :-)

1 can you ping from another computer to yours..?
2. have you checked your hosts file..? C:\WINDOWS\system32\drivers\etc\hosts
have you ran from both your computer to another and from that pc to yours the command

tracert %ipaddress% where %ipaddress% is the ipaddress of the 2 computers
eg Tracing route to www.l.google.com [66.102.11.104]
over a maximum of 30 hops:

  1     1 ms    <1 ms    <1 ms  192.168.0.1
  2    19 ms    18 ms    17 ms  10.20.20.229
  3    19 ms    19 ms    19 ms  bri-nxg-alf-csw1-vlan-1.tpgi.com.au [220.245.180
.193]
  4    19 ms    19 ms    23 ms  bri-nxg-alf-crt-2-port-channel-5.tpgi.com.au [20
2.7.162.133]
  5    36 ms    36 ms    36 ms  202.7.162.30
  6    36 ms    36 ms    35 ms  202.7.171.18
  7    38 ms    37 ms    37 ms  66.249.95.224
  8    49 ms    37 ms    36 ms  64.233.174.242
  9    36 ms    36 ms    36 ms  syd01s01-in-f104.1e100.net [66.102.11.104]

Trace complete.

if the issue is not occuring on other pc's i would not really try uninstalling your virus scanner
can you reimage the machine..? mabye the fastest fix

p1339:
Haven't checked the hosts file. All other network access is fine which would suggest that it's not a hosts file problem. Tracrt doesn't work for any hosts either - get 'host unreachable' but I can see that DNS is resolving addresses correctly.

we need to see information..

can you ping from another computer to yours..? this 1 is important..
what do you get with your ipconfig..?

instead of everything works fine we need to see data.. there may be something in the data you see as fine and we notice :)

QlemoBatchelor, Developer and EE Topic AdvisorCommented:
I reckon it is time for a network capture on that machine, filtered for ARP and ICMP. A ping of the gateway would be fine there. Interesting part is whether the gateway sends ICMP "Host unreachable", or it is a timeout (no answer), or the reply does not match the request (e.g. MAC addresses, IP address, ...).

Problem caused by McAfee firewall, despite it being turned off it somehow interfered with Ping - even with the McAfee firewall service disabled. Removal of McAfee returned ping to normal. Strange how this doesn't affect other PC's in the office with the same McAfee software and the same rules.

optomaCommented:
Just happens sometimes and the easiest way is to use removal tool + test, which worked in this case!

Did you reinstall McAfee and if so, all ok?

BeehiveITAuthor Commented:
Optoma: No I only uninstalled the firewall component and no I haven't reinstalled - switched to Windows Firewall which I prefer in a domain environment anyway. Live and learn!
