Which means your NIC works with Debian. That's good.

Run "lspci" while attached to the docking station. Look for an entry
mentioning your network card. You may need to "modprobe <module>", where
<module> is the name of the appropriate module for your network card.
You could also run "modconf" (if it's installed) for a more menu-driven
pick-and-choose method of installing the correct module (and this method
has the advantage of adding the module to "/etc/modules" so it'll be
loaded on succeeding reboots - otherwise you'll have to add it manually).
I think that nowadays there's a utility ("discover"?) that should
automagically probe for and insert correct modules on boot-up, but it
may not be working properly for you for whatever reason.
Once the correct module ("driver", in Windows-speak) has been loaded,
you may still need to restart your network, with "/etc/init.d/networking
restart". You may also need to define your network settings in
"/etc/network/interfaces".
I know this is not very specific, but it might point you in the right
direction.
