I have two network cards in one computer(1) in my network where one of the cards give a cable unplugged messege. I also have another computer(2) in my network with two network cards aswell with the same error situation. It seems that when I disable one of the network cards in computer 2
then the net cards in computer 1 work fine with no error messege. one network card on computer 1 and the net card on computer 2 are have the same subnet(A) and the other two are in their own same subnet(B). The added routes seem ok but what could be the problem? one of the subnet goes thru a sonic wall to connect to our remote site.

your topology is mesh?

for redundancy?

are the nics directly conencted with cross overs or thru a hub or switch or router?

if you have the computers pluged in without a device between them, the connection without the sonic wall,


it says network cable unplugged because it can not detect a signal

are you sure the cable is good and is a cross over cable (different then standard ethernet cable)

One thing you might want to do check the Mac addresses on your network cards.  As unlikely (and I mean VERY unlikely) that both cards have the same exact mac address it has happened before (I once spent a week trying to figure out why 2 computers would die off the network if they were on at the same time).  Open a DOS window and type ipconfig /all and note the mac address for each card.  Make sure they are not the same.

You can also try swapping the ip/subnets of two lan cards on one machine(i.e. either 1 or 2) and see if it gives same result.

Thanks everyone but I have finally solved the problem. It turns out that the problem was with the hp 8  port switch was not able to handle a lot of activity or was it could have been a bad switch. As soon as I put in a hp 24 port switch the problem went away.

Thanks for all your help
