I have a few laptops sharing the same problem. All have Windows 2000 Porfessional installed and have two network cards each. One is in the docking station and one is in the laptop. I cannot always connect to the domain whether I am in the docking station or not. It seems that once I can connect through the docking station I cannot connect the laptop when disconnected from the docking station. Some help would be really appreciated!!!! Thanks.
