Windows 2000 won't ping anything on local subnet

[msdonb]

I've got a laptop running Windows 2000 with an integrated NIC and a Netgear Wireless PC Card. The laptop gets internet, but won't see anything but itself on the LAN. I can't ping any other device on my LAN, nor will it resolve any windows workgroup computer names. Nothing else will ping via IP except itself & loopback. But it's GETTING its IP from a dedicated DHCP server? Yet it can't ping the DHCP server!??!? WTF!?!? Any ideas?

Pull the wireless card and see what you get.

Tried that... still nothing. I've also tried uninstalling/reinstalling all the drivers/hardware. I just took the thing to jack in the box to use their wifi and VPN'd into my network. From an outside IP everything works fine. However, when I plug into my physical LAN, i get nothing. The DHCP server is assigning it an IP address, and there's a gateway allowing it to get outbound to the internet. Internet works, but nothing on the LAN side functions. I can't even get other machines to ping it once it's connected. Strange, I'm having the exact same problems on both laptops. (Identical DELL Latitude configurations, aside from processor speed)

Typically you can't run a wireless and a wired at the same time. When you plug in at home, are you sure the connectivity you see is not coming from the wireless?

What do you get with

ipconfig /all

?

As you can see, each NIC gets its own IP address from 192.168.43.15, yet it can't even ping that address. Frustrating! Same problem on TWO different laptops... both were reformatted recently with new OS/patches/neccessary apps. Dialup & VPN both work on the LAN, but then again, they are outside/external IP addresses pinging inbound. DNS is working fine, as you can see I can ping outside IPs and the internet works flawlessly.

I'm not sure what the problem is, but I would pull the wireless and get the wired connection working first.

[msdonb]

They both do the exact same thing. Whether it's ONLY the wireless or ONLY the wired ethernet. Exact same response. :\

 

[GlenJohnson]

What have you got set up for security? Something is blocking this, and I'm guessing it's software. Give the laptop a fixed IP and see how the software likes it. I'm guessing someone on the server is going to have a hissy fit. Good luck.

Can you ping your own adress or 127.0.0.1?

It works! Now if only I could remember what I did...

[burtsbees]

If it ARPs, then he should be able to ping the loopback, showing the IP stack is all there. This really sounds like the server and gateway are blocking ICPM echoes, but only if it does this on other workstations as well... Have you tried pinging the laptops FROM the server and gateway? Do other workstations have this problem? Is Norton running on the laptops? Even Worm Protection? I had to shut worm protection off on mine to be able to FTP to my FTP server at home!
One other thing to consider if the two laptops are the only two doing it---System Restore to before the patches were installed then try it. You did backup/create a restore point before installing the patches, right???

[Bas1234]

Could it be that you used the same IPadress on your laptop/PC as the one in the Switch?

First, you would get a Windows Duplicate IP warning. Second, one of them would do nothing. Both work.

[msdonb]

They are NOT duplicate IP addresses on the network. The DHCP server is assigning these addresses and all adapters are being assigned unique IP addresses. It's so wierd that I can see an ARP table with various devices/IPs listed, but can't being anything but the host itself. Yet I can ping anything OUTSIDE the subnet. There is no security setup on the laptops, this issue presented itself long before I installed any virus software/firewall stuff as I thought that would be to blame. I'm wondering if it's the VPN client that's causing the issues, we're using an Adtran Netvanta VPN client and it's almost impossible to uninstall though. I guess it's fine for now since the laptops are primarily being used outside of the building and everything seems to work fine when it's using an IP other than the one on my LANs subnet. :\
