NIC problem

[vacunita]

I have a computer than suddenly lost connectivity to the server. Were in a small LAN 10 workstations(Win98,WinME,2000,XP), 1 Domain server NT4.

The PC in question (WinXP) shows the Network cable unplugged icon. However the light on the switch is lit.

If I connect the PC to a testing hub I know works, along with another computer for pinging, it shows the connection icon as active, but can not ping anything.

I've checked the port on the switch, and it works as if i connect any other PC to that port it connects to the server and can ping anything.

So I'm fearing that the onboard NIC may have failed, at some level, but somehow still functions enough to pick up the other hub.

Anything else you can suggest I check?

Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

I used a different cat5 cable that I know works, to test, and it's now picking up the DHCP from the main switch, but I'm getting a lot of packet loss when I ping.

I'll get two Replies at best from the 4 sent every ping. Any idea what may be causing this? as no other PC's in the network exhibit this behavior.

And this packet loss is enough to disable an app that connects to the server for data.

It's your NIC in all likelyhood. The light on your switch is only looking for a terminating resistance supplied by the NIC; it is a layer 1 check with no intelligence.

I've seen your symptoms many times, it has always been a bad NIC for me.

Well i guess i can install a PCI NIC. into the machine. I wonder what could make the NIC just loose it overnight.

No real telling, but as I recall I've never lost an add on NIC, only onboard ones.

Sometimes the TCP/IP stack gets corrupted.
Install another NIC protocol, like IPX and then uninstall and reinstall TCP/IP onto your NIC and see if that fixes the problem.

This one is out of date and probably resolved.

TCPIP can't be removed. But it can be reset.

You are probably right as far as it already being resolved.
I was going to take issue with you over the stack removal since I have done it several times, but I went into my LAN properties on my XP machine and sure enough, it wouldn't allow me to remove it.

They must have locked it in on XP because I know you could remove it on the earlier windows.

It just shows I'm not keeping up, I guess.

It's a challenge for sure. And I haven't even looked at Vista yet.

The reset cleans up a world of issues and gives you a log file of what it has done.

I found it trying to resolve a two machine network problem where the issues kept getting worse until one finally lost contact.

Make sure the nic speed/duplex settings match what is configured on the switch . If the switch is auto then the nic has to be auto and vice versa if the switch is hardcoded you must hardcode the nic settings to match .

Thanks for the info and update edfair!
