There's nothing to stop you simply openeing the .pst file from the main PC on your laptop. This will not take it over or import it - simply give you a view into it, as well as the loacl .pst file.
In Outlook2000 - File - Open - .pst file - then browse to the remote file.
Since pst files are not shareable though, you won't be able to write to it from the laptop - not that I would suppose you would want to.
Please note - all this is from my memory of doing it in a very similar setup to yours - I can't actually try it out here, as I don't have such a setup.
