I am running on XP with SP3.

The icon tray at the bottom keeps flashing Local Area Connection balloon with "A network cable is unplugged"

It flashes about 15 times per minute, sometimes more.

I've tried a system restore to earlier points and no dice.

I've tried to find the driver :) :) but a search on the system disc and the computer gives up looking for the driver that it came with!!!!! Can't seem to find it!

Naturally, in the device driver on the system tab it announces that the device is working property.

Please help me. This is really annoying.

Troubleshooting 101 - make sure the physical connection is good. Great that you mentioned this. I initially made sure the cables were seated correctly in their sockets [and connected] but the one thing I didn't do was to switch a known good cable. Great idea. I used a known to be good cable that I am absolutely sure is good but that did not fix the problem. Even though it would have been embarassing, I wish that was the fix!

That didn't work. Need a plan B.

Limited or No Connectivity go here and try the suggestion at the beginning to see if it helps. If not post back and we can continue on.
You may be experiencing a failing nic card in your system.

Can you provide system info like
Make and model if a branded name system.
If not a brand name then we need to know the make and model of motherboard.
Is your nic card built on board or is it a add on card?

Neither tactic worked - renewing the address and powering the router on and off.

Here is the systemm info:

Systemax Ascent KMA3500

AMD A64 X2 3600+ 2.0Ghz AM2 PU
1GB PC5400 667MHz DDR2 Memory
K9N6SGM-V MCP61 mATX Motherboard
MBO I/O SHIELD K9N6SGM-V
52X32X52/ 16X Combo Drive
Optical Acroll Mouse USB
running MS Windows XP
HDO 80GB SATA 3G NCQ

Integrated 10/100 Network Card

If the integrated card is shot- would the work around be to install a NIC in one of the slots?

You are 100% correct in your assumption.
Make sure you get a 10\100 BaseT card. Most likely it will need to be a PCI card.

I am going to get a NIC and install it tonight. I'll let you know if that solves the problem.

Thanks.

The card I thought I had at home was wrong. I am leaving for a 3-day business trip tomorrow and I didn't have the time to get the card tonight.

I'll get it Saturday or Sunday and then let you know Sunday night.

Sorry for the delay

I bought a Linksys 10/100 PCI Etherfast card LNE100TX and installed it.

"Local Area Connection3 A network cable is unplugged." still comes up as an error repioort.

Now What?

Tyhe only difference is that it says "connection 3 in the error message instead of just connection. Where did the "3" come from?

I'm kind of at wits end that this message is still coming up.

The connection does seem to cut out briefly.

The next thing I would suggest then is to check your modem or router to make sure they are good.
Disconnect them completely from power for about 5 minutes and then reconnect. This will cause it to hard boot and hopefully clear any issues.

OK I turned the router off for at least 5 minutes and then powered on. The error message appeared both before and after the reboot.

Now I get the message the POP server has not responded for the past 30 seconds...

Turned off or disconnected from power and cable?

I turned off the router, pulled the plug from the power source to the router. Waited a good 5 minutes, plugged the router back in, turned the router on.

Openned up Outlook asnd the messages came popping up same as before.
