Local Area Connection has vanished

[williamholab]

I have a workstation with Win XP (sp2) and the Local Area Connection is gone. I ran the setup wizard to create a new one, and it finishes without reporting an error, but nothing appears in the Network Connections window, and there is no connection. I checked the following:

All cables/connections (replaced them)
Lights on the card (all solid green)
Diagnostics for card (all "pass")
Hardware configuration (functioning properly; driver is updated)

I ran the setup wizard many times, but the result is nothing. If I shell out to DOS I can't ping anyplace on the network and there is no IP address for this computer.

Any suggestions? What am I missing?

Tx!

hmm.
first do you get your internet through ur LAN if so. then just try going to Internet Explorer or watever web browser u use and start it, reply back if you can access the internet.

"and there is no IP address for this computer."

now about this. if your LAN isnt connected to the internet there wouldnt be a IP address.

I have internet access on the other computers on the LAN, but obviously not this one. I tried pinging the gateway and it won't respond of course. This computer was working fine on the network 2 days ago. I'm thinking the network card suddenly went bad, but the diagnostics said it was o.k. so it seems like that isn't the problem.

do you have a firewall on your computer?

That's utter rubbish!

A Windows based LAN works on TCP/IP...therefore all computers will have an IP, irrespective of internet connection!

Try popping the XP CD in, and running:

sfc /scannow

It's like doing a repair install, but easier.

Then try making the network connections again.

Have you got a (working) spare NIC you could try?  Might be worth the 10mins.
