That is been what we have been thinking all along. The last card that went out was the first since we put surge protection on the interface. This last card that went out simply wouldn't answer, the interface worked fine. All the other cards that have gone out, the interface would go out, but the card would pick up and you could still check in the VM manually. We were thinking maybe coincidence that this last card quit working, since the interface had nothing to do with it.
