Lose it's connection as in &quot;A Network Cable is unlougged?&quot; error on screen by the Systray?<br />
Or, just inability to connect to certain resources....?<br />
<br />
Think we need to clarify that....<br />
<br />
If it's a physical thing... Have you checked the cable to the wall? Connection to the switch (maybe try another port?)? Duplex settings on NIC? Does it match the Duplex settings on the switch port?<br />
<br />
Assuming you have checked these, but still wanted to ask....
