Network Cards show Disconnected, but machine is still connected and working

I have a 2 year old HP DL580 G3 server with a pair of 1 GB nics that are set up in as a team.

I have notice a few times now that the individual network cards will both show as disconnected (as in no cable plugged in to the card)  while the team still shows as connected. the machine is not actually disconnected as it is up and working while it shows disconnected and no errors are logged by either windows or the HP monitoring software.

It just started doing this and I would like to figure out why. If anyone has seen this behaviour before and has a solution could you let me know please

Also I should note the machine is running Windows Server 2003 x64 and SQL Standard 2005 x64

I believe it is normal - from OS point of view the operational interface is Team, not the individual NIC cards. While at least one of Team member cards is working the Team is operational.

I don't believe this is normal, after a restart the individual cards list as being connected for a few days before they all of a sudden show as disconnected. and for the past 2 years it has always showed as connected.

also over the last 2 weeks we have been having a strange issue with a web app on a different server suddenly being unable to connect to SQL on this machine. I have no explanation for the problem as I can't find any problems, nothing is logged on either machine and the network appears to be working fine.

I am starting to wonder if I don't have a problem with the team network card or if one of the individual cards might be developing an issue?

What happens if you plug the cable to the card that was disconnected? Is status changing?

Sorry, I misunderstood your initial post. I thought one of the cables is disconnected.

Maybe you could start troubleshooting this by breaking / recreating the Team.
Also,  have you tried to install the latest HP Teaming driver?
