I have two identical laptops and two different docks. I am having the same problem with both laptops. Both docks have the same ethernet card. This is the problem. Starting from scratch I plug in one laptop into dock1. The laptop recognizes the ethernet card and allows me to set it up (Ip address etc.) This all works fine. Then I put this same computer into dock2 and the laptop now tries to install another copy of the same ethernet card. It only has one card in the device manager, but puts two in the network control panel. When I go to setup the ip address for this dock there is only one card in the tcip section. If I go to the bindings for the cards the first card I set up has all the bindings present and checked. The new card only has one binding, and it is not tcip? So how do I get the laptop to work in these two different docks with the same ethernet card.
